Welcome Jamie.
You need to take care of yourself. Perhaps a professional counselor can help you get through this time in your life.
If you really want to go back to meetings and be a member of the congregation in good standing you should build your physical and mental health up. You need to be strong in both areas in order to make it. It's tough going to the kingdom hall while disfellowshipped.
-As a side point; there isn't actually any proof that the man in 1 Cor. is the same person mentioned in 2 Cor. It is a correlation the WTS makes and probably some other religions too. But, if you research it a bit it is also possible that Paul was talking about himself. He seemed to have a love/hate relationship with the Corinthians.
Welcome to the board and good luck on your journey.
