Some thoughts:
1. Your mom may simply need to be educated. Most people have heard of transgender but don't really know what it is. Make sure she knows:
* Transgender isn't something you choose. It's something you're born with.
* Transgender is serious. Depression, anxiety, and even suicide are common among people who ignore it.
* There is no cure. No one has come up with a way to make it go away.
* The only treatment is to transition and live as your true gender.
2. She may need some time to absorb this. During this period, DO NOT HIDE IT FROM HER. She needs to understand that it is your reality whether she likes it or not.
3. If she truly loves you, she will not want you to live in a way that is not true to yourself.
4. But in the end, you can't control whether she accepts you as trans. You can only control what you do.
5. Most important: If you live your life being true to yourself, in time she may accept you, or she may not. But if you hide your true gender from her, she will never know who you are and therefore never accept you.
6. Being unsure of a parent's continued affection is really hard. Please give yourself credit for dealing well with a tough situation.
Good luck, Ronnie. Please keep posting and tell us how it goes.
