The Byzantine pretty much said it all. I just wanted to add that the people you will be speaking to are professionals who are there to help you. Nobody is going to lock you up and throw away the key. They want to make sure you and the people around you are safe, and to help you get better, just like when you see the doctor if you've hurt yourself, their priority will be to treat the wound. Just be honest with them -- let them know that you're nervous or unsure, if that's how you're feeling. I'm really glad that you're seeking help, it's a wonderful thing you're doing for yourself!
