Good luck Dub.
I'm glad to hear that you have friends you can talk to. It's important. Be careful about the baptism thing. Once you're baptized you can be DF'd or they can say you DA'd yourself and then the shunning will start. Fortunately your mom will be there for you no matter what.
Remember, your dad is trying to do what he thinks is right. Maybe if you put yourself in his shoes and respond to him with that frame of mind you will make some headway.
Again, good luck.
