If you have truly repented, then it's a done deal. God has forgiven you. As Jesus said to the woman caught in adultery, "Then neither do I condemn you. Go and sin no more!" You are forgiven, and don't let the devil or any person acting on his behalf tell you differently!
Right now, you need the love and support of a church family. Your feelings that your current church may not accept you may be just lies that the enemy is whispering in your ear. I would encourage you to at least talk to someone there that you trust. If you get the vibe that they are not going to support you, but rather judge and condemn you, then maybe it's time for you to find a new church family...
Also...I highly recommend Anne Lamott's essay, "Why I Make Sam Go to Church." Yes, Anne's opinions are sometimes a bit too liberal for my taste, but this is a great essay about how she found a church family that would support her when she found herself unmarried, unemployed, and pregnant. I believe it's online if you Google it!
God bless you and your family!!
