So my faith is a pretty big mess; I’ve fallen back into a lot of old habitual sins, I’m hardly praying, and I’m really doubting God altogether. I want to go to confession because I have a real lot to confess and I guess maybe I’m scared not to go, but I’m not really sorry for all my sins. At first I felt horrible when I sinned, but as more time has passed, I’ve just gotten more and more indifferent and started sinning more frequently. Part of me wants to come back to God and the other part is screaming that God can’t exist, the faith is ridiculous, and it’s caused many of the problems in my life. I feel like my life is so tangled up that I don’t have the strength or the courage to work it out and I’m really ashamed of some of the things I’ve done. I’m not sure that I will make an honest effort to start fresh after confession; maybe I’m wrong, but I feel too weak and tired and confused. I almost think I would be a better and healthier person without God.
Is it ok for me to go to confession when I’m feeling like this and I’m not 100% sorry for sinning? Somehow it seems wrong to me. I keep waiting for contrition to come, but instead I seem to be moving in the wrong direction.
p.s. I know I posted a couple weeks ago about going to confession after daily mass – I didn’t go, I just keep putting it off.
Pray for grace and then make an appointment and go sit down with a Priest and talk…(the actual sins may be something to wait until the actual confession --so they are under the seal)
Remember contrition is more of the *will *than feelings (feelings need not arrive but one can have very good contrition). And imperfect contrition together with of course a firm purpose of amendment etc (talk with the Priest about his) can be had …even for lesser supernatural motives like fear of hell…
Temptations come differently to one who is actively living a Christian life --than one who is caught up in his gravely sinful patterns …that temptation is more lulling of conscience to sleep…
Resist --and make that appointment! Lay your difficulties out…
PS: the Priest has heard much worse.
But know that in Jesus Christ and thus in his Church is true life.
I think it would be best to make an appointment to go, so you will have a bit longer time during confession to talk about some of the issues youre experiencing. I would just frame it just as you have here, that you are confused and not sure if you are sorry for sins x y and z. I have actually mentioned my struggles with certain sins being considered sins during confession, and received very charitable advice from the priest. Over time, I feel I have received much grace to get a new perspective on those sins…however, the grace did not come without a lot of lapses back into sin, as well as resulting shame.
When in doubt, go with the shame. I feel that emotion is an indicator that we are on the right track…
I’ll pray for you tonight.
OP, I am much like you these days…tired, confused, doubting. I go to adoration every week, and just complain and then feel foolish that I’m complaining to a circle of wafer at 1:00 AM when I could be home sleeping because I’m so tired. I hope God is real, and that He & Jesus forgive my lack of enthusiasm.
We can be sorry that our sins offend God, not so much that we ‘feel’ that whatever is so terribly wrong. That realization comes with time and reflection. So, for now…I’m sorry that my sins offend God.
I don’t think it is helpful to add adjectives to “sorry” or our level of contrition. Certainly, we must be sorry for our sins in order to benefit from Confession. However, to be “truly sorry” or “totally sorry” or “completely contrite” is not demanded of us before we can confess. Yes, a traditional act of contrition says “I am heartily sorry…” but if a person left out the word “heartily” it wouldn’t necessarily mean there was no contrition.
Staying away from confession because of imperfect contrition is not wise and is not demanded/suggested by the Church. A reason we have this Sacrament, after all, is to enable us to be forgiven even if our contrition is not perfect.
Among the penitent’s acts contrition occupies first place. Contrition is “sorrow of the soul and detestation for the sin committed, together with the
resolution not to sin again.” 
When it arises from a love by which God is loved above all else, contrition is called “perfect” (contrition of charity). Such contrition remits venial sins;
it also obtains forgiveness of mortal sins if it includes the firm resolution to have recourse to sacramental confession as soon as possible. 
The contrition called “imperfect” (or “attrition”) is also a gift of God, a prompting of the Holy Spirit. It is born of the consideration of sin’s ugliness or
the fear of eternal damnation and the other penalties threatening the sinner (contrition of fear). Such a stirring of conscience can initiate an interior process
which, under the prompting of grace, will be brought to completion by sacramental absolution. By itself however, imperfect contrition cannot obtain the
forgiveness of grave sins, but it disposes one to obtain forgiveness in the sacrament of Penance. 
In my understanding:
If you detest you sins because they are ugly or because you fear damnation then you have imperfect contrition. This is sufficient to forgive venial sins but not mortal ones. If you fear a sin is mortal, please talk to your confessor/ parish priest. That is what they are there for. It is best to talk to a priest you do know so they can give you more personalized help.
Fear of hell, determination not to sin again, and the sacrament of penance are all that is needed for the forgiveness of venial sins. It is the mortal sins which require perfect contrition. If you have doubts you still may be surprised by the wisdom a priest has. They don’t go through at least six years of training and schooling for nothing!
p.s. Don’t be ashamed or feel unworthy to go to confession. It is not for people who are perfect! It is for sinners. I can tell you from experience that it really gives you strength. Don’t go if you do not at least have imperfect contrition or if you do not believe, but do not hold back from shame or a feeling of unworthiness.
What about confessing to the fact you don’t feel sorry? If this troubles you, you obviously want to feel sorry, and have a conscience about the fact you can’t.
Sometimes a good confessor can put their finger on what stands in your way. I remember confessing to the fact I didn’t want to forgive certain people. My confessor was able to identify what was preventing me from doing so - the desire for revenge. He also enhanced my understanding of what forgiveness is, in that forgiving someone does not mean forgetting what they did or not feeling hurt. He said that would not be true forgiveness, as true forgiveness does not mean telling people what they did was OK.
Once you know what stands in your way, you can deal with it. If you don’t know, you can’t
and that’s were a good confessor can point you in the right direction. I also remember a monk who visited our parish telling us about a young man who came to confession, hadn’t been for a long time, and he got the impression he didn’t really want to be there and wasn’t sorry. When leaving confession, the young man said ‘I’m glad I came.’
The point of his story was going to confession isn’t a complete waste of time, even if one thinks it is. The other thing I would say is confession isn’t always a wonderful experience. It can be a real struggle. It doesn’t mean you have to give up.
