(Post 2 of 2)
it's not easy to overcome the sins of the flesh once you've given yourself to them, but remember that with God all things are possible, and He will help you whenever you ask, and give you all the grace you need, He never ignores a sincere cry for help, so whenever we do fall, it is not because God did not help, but because either we did not ask, or we did not accept the help he sent.
but just stay hopeful, and try to keep your peace, don't let yourself get anxious over this, just do what you can, God doesn't expect anymore than that, doing your best is the best you can do,
and also remember that God is not as displeased with us for falling from weakness, as he is when we fall on purpose and don't care, we are all weak and sinful creatures, and our strength comes from God alone, so that's why we must never neglect to pray when we are tempted, because without God, we cannot overcome even the smallest temptation...so when you do not ask for help, this is what you can expect from yourself, so you must try to see yourself as you are, weak, that is humility, seeing yourself as you are, seeing the truth, humility is the virtue of truth, whereas pride is the vice of lies, and it's not a bad thing to be weak, nothing to be ashamed of, it's just that when you acknowledge what you really are, then when you do fall, you can say "Lord, i fell because i am weak, and did not ask for your help, please help me to do better next time, and i resolve never to commit this sin again" a resolution is not a promise, but an earnest decision, so don't worry if by weakness you do not keep it.
It's very possible though, if you take the right steps, such as the things i've mentioned, and what your confessor tells you, that you will not commit this sin ever again, but remember, that at the moment you think you have overcome this, when you are most confident, that is when you must be on your best guard, because it is then that the devil tries even harder to make you fall, and when we are confident, that's when we let our guard down.
another word of advice, don't think of sins of the flesh, don't look back on them, because by bringing them to mind you set yourself up for temptation, and if impure images, such as billboards, woman dressed immodestly, and those kinds of things, are a big temptation to you, then keep your eyes down, don't look up unless you have to...just try to have custody of your eyes, it's not unheard of, even the saints recommend it, and have done it,
and the same goes for tv or internet, whatever poses as a temptation for you, stay away from it, we don't fight temptations to impurity, we run from them, because to fight them is usually a losing battle.
ok, sorry i wrote so much, but i hope it helps, and if you have any questions, i'd be glad to discuss this further,
