1) Priests live a lonely life
Lonely, I hope not. Solitary to an extent, yes. Loneliness is a despairing solitude. If one is uncomfortable being alone, one should not be a priest. It's lonely at the top, as some leaders say, and priests are leaders in their communities. Priests spend significant time alone, either in prayer, or working.
2) Priests are overworked or overburdened
There is probably more truth to that than I would like to believe. With the shortage of priests, yes, there are many single-priest parishes that have 2000, 3000, or even 5000 parishioners. That's a lot of shepherding. Not to mention administrative duties, which, thankfully, laity can help with a lot. But yes, there is a lot of work. Saving souls requires all forms to be signed in triplicate.
3) Priests are no longer respected by society
By some of "worldly" society, yes. But within the Church, priests are still very much respected. However, priests don't answer this vocation for glory and fame and to have people like them (I hope). "Society" doesn't like people telling them they can't do what is wrong to do. Jesus had a couple words to say about this. "The world will hate you because of me," or something... Might have been a prominent theme in all four gospels, and maybe acts and the letters too.
4) Oath of celibacy is taken by primarily feminine or gay men
I don't have a nice response stronger than "hogwash." As per the 5th edition of the Program for Priestly Formation published by the USCCB, in response to urges from the Vatican, a candidate for ordination cannot have homosexual attraction. What was that? Homosexual men will not be ordained. Why? Not because the Church is a bunch of old homophobes. Not because of sexual scandals. But because a priest is a father, and how can a man be a true and holy and good father if he has no concept of what real fatherhood really is? Mother Theresa was quoted once as saying "A woman who has no desire to be a mother has no business being a nun." Well, a man who has no desire to be a father has no business being a priest. Priests need to be strong, firm, and loving men. Not wishy-washy and effeminate. Christ is the High Priest forever. Behold that Man, and see what the image of the Father really is: one who is ready to suffer for his children.
5) Priests are now unable to show any affection towards children
Hogwash, to steal the words of an above poster. Certainly, men in the Church must be careful how they display affection, and not give cause for any scandal. However, we can't live in fear either. It is all about building good relationships, ones that can be public, not ones that you feel can only be displayed in private where no one is watching. If you feel you can only display affection when people aren't watching, there is a problem with something. That said, people do have to be careful. Not just those in the Church, either.
God bless you in your discernment.
