Pope Benedict XVI is cleaning house, and taking care of this and the other problems. The Church will be as it should in a couple more years. We would always be happy for you to return. Just remember that the Church is perfect, but men are not. The Church is a haven for sinners, as it should be. They need Christ more than the righteous.
2 -- Being brought up Catholic means constant guilt
It's not easy being Christian, especially in these times.
3 --I feel like I should go to Confession
Go for it. It feels like the weight of the world has been lifted from your shoulders afterwords. I admit I don't actually enjoy going through it, but it must be done, and I am always happy I went afterwords. God bless.
It was very difficult to get through my first one, and then I went two more times before I was received into the Church on Easter. I now try to go at least once a month.
The thing I appreciate about it, besides the things already stated, is that the examination of conscience and confession come to your mind when you are going about your week, and often keep me from further sin. (Not always, of course, but I certainly don't want to be confessing the same thing over and over again. )
