I might get downvoted here, but I have known people that game being trans/LGBT and I know someone that went through with transition not because they were trans but because their gf wanted it, it was her kink.

So these situations do exist, but your feelings are valid and if you feel that you are trans, you may well be. You should try to see a counselor or therapist in your area, tell your parents it's for depression or something else that's unlikely to raise suspicion. Your therapist can help you come up with a plan and potentially create a neutral environment for you to bring one or both of your parents to eventually to break the ice if that's needed.
