Hi H and welcome to Susan's. There are discussions around coming out, see Forums->Transitioning->ComingOutOfTheCloset. Susan's is a very welcoming place, we have come together here to support, share, vent and even laugh. I fully get that you are scared. Been there, still am sometimes. Not to worry dude, you will get a lot of answers here. My first suggestion is, if you don't currently have a therapist, find one. They are a huge help.
