Satan is really, really good at ferreting out our weak spots, isn't he? When I read your post, I thought about the armor of God (Ephesians 6:10-18). I think it shows wisdom that you see your worries as a possible attack. If you see it coming, you know how to fight it, and I believe these verses can give you some clues. And, remember these two things: God never ever forsakes you, even if it doesn't "feel" like He is there, and if you resist, Satan will flee like the coward he is.
As for the second coming, I understand your feelings. When I first became a Christian, not only did I dread that, I dreaded the idea of spending eternity praising God. But, as my relationship with God matured and deepened, my views changed. I'm still not happy that people will suffer, but I trust God, that whatever He does it will be the right thing.
I totally agree with L4H--you should try very hard to get to church. Other believers will be able to surround you and help you grow. As well, you can talk to someone you trust (a Christian) about your fears, and have them pray for you. Also, read your Bible, as this will give you truth in the face of the lies Satan tries to throw at you. Pray that God would turn you into the kind of person He wants you to be (trust me, He'll do it, even if you feel like you're only 25% sincere when you ask).
