Like the others have said, you are fighting hard against transitioning, and the big question is, why? You haven't given us any family background or personal history, so it is not really possible for us to offer anything more than guesswork about your situation.
The panic attack (I don't know what else to call it) prior to going in for hormones is an indication that there is something going on with you that is very much against transition. The question is, is it family, is it religion, or is it something else entirely?
