What Karen's saying is true... People want someone to feel superior to. Everyone in my home town is jealous of my life--owning a home so young, making money doing what I love, engaged and fully independent of my parents... My parents are both proud to busting about my career and that I'm succeeding at something they have both failed at, making a living as an artists. My friends have always viewed me as the most successful and mentally healthy person in our social group. I have shown them that thought I don't do things the same way they did, I come out on top. I went to college late and haven't really been trying too hard to finish, and I was almost held back from graduating high school because of attendance issues, and though people didn't like what I was doing they saw that ultimately everything I have done has contributed to me making all my goals way before than anyone esle... So when I came out as TS, nobody could tell me what I was doing was wrong or a bad idea. I'd shown them time and again that no matter what they thought, I was making my own way and iit was all going to turn out fine. Everyone has taken it on faith that no one can know what's best for me better than I do myself.
I *know* the reason they're all so cool with it is because I've shown them all wrong before, so they trust my judgment more than their own feelings on the matter, and they know this is my life and not theirs. And it's also because I don't let anyone else's feeling of self-worth depend on me or my opinions. I used to have some friends who would say things like "Oh, if something ever happened to you or if you didn't like me anymore I would kill myself..." THAT is unhealthy. That's not a good thing for them to feel and not a good thing for you to feel responsible for. I think your mom's need to keep her name clean is entirely her own problem, and the fact that she can't differentiate between her honor and that of those associated with her is HER fault.
The best way to put her and the rest of your hometown where they belong is to live your life to the fullest with or without their consent. It IS your life, not theirs, and they may learn something in the long run 🙂
