Oof, that seems like a lot. You are perfectly valid, no matter what gender, sexuality, etc. you are. And it's not 'wrong' or 'bad' it's just the same as identifying as male or female. Your parents may not support you, but eventually, you'll move out, make decisions about your gender and/or sexuality now that you know more, start a family, and not have them to worry about.
Hope this helped!
