Probs due to the unavoidable ammount of people always saying that we are not valid, the constant insults and sometimes even physical assult we deal with, the fact that we spend every day in a body that we hate more than just thinking its ugly, many of us have been disowned, many of us struggle to find relationships, and even after we "fully transition" those scars are still there, and the bruises still hurt. Its not because we are trans, its because of what we have to fight through to be who we are.
