Everyone has something in their lives, either past or present that they don't want anyone to know about. The problem is that you can't always hide that unless you change where you are. Believe me, I know what it is like to be so dysphoric and trapped that there seems to be no way out.
People who knew you in a male body, still have that image, and its not something that you can escape sometimes.
You certainly look like an attractive young woman, and for those who didn't know you in a male body, I doubt very highly that they would ever suspect.
You may like where you live, both the immediate area and state, but sometimes you have to get away from people who knew you before. You don't have that far to go. Getting an apartment a half hour away from where you presently live would go a long way in getting rid of those who know you. That seems radical, and it is, but if it came to the difference between you not having to feel so oppressed and dysphoric, it may be worth it. Even getting a job where no one knew you before and remaining to live in the place you are in is an option.
I don't know where you are surgically or if you even want that, but getting in a area that doesn't know the body you had would probably help. If you are legally changed, then there is no more need to tell anyone, and unless its your Dr. or a serious relationship, keep it to yourself.
There are very few people that can get past something that "weird". They have never had to live with it and there is no way they could know how they are making you feel. Your past is no one's business but yours, and you can't afford to continue taking hits from ignorant people. You need to get your self esteem back first.
Honestly, I'm not trying to make light of how you are feeling or the abuse you have taken. Get enough people telling you that you are a fake or some other derogatory words and it starts to do damage. Sometimes we have to be selfish because no one else is going to change things for us. Realize that its the people calling you names that are the losers. If they fear you, which is a big reason for rejection and name calling with this issue, then they are weak and you are the strong one.
I think everyone here has had similar experiences, and though we are online, we are here and you know you can always reach someone. I've posted at two in the morning and gotten answers. Please don't let ignorance convince you that you are not worth anything or aren't really who you say you are. Being a transgender is not easy, before or after transition. Its a matter of finding a way of m ;)aking peace with yourself and ignoring the ten year olds in adult bodies that have to put someone else down to make themselves feel better.
