Asher,
I'm Laurie. Having family members that do not accept you for who you are is a really hard thing to deal with. But I don't need to tell you that because you are having to do so. I'm sorry and know how you must feel. It feels like hell, your world gone upside down and inside out. Having those that have said the love you all your life not willing to help you with one of the most important things of your life. It hurt. It hurts so deep inside you don't know if you will ever be okay again. And it could even feel worse than that. I do know what it feels like, because I feel it too.
It sucks! There is one difference in our circumstances. In my case, I've lost my daughter and with her, my 5 grand children. So my dear Asher, you are not alone in feeling as you do. There are many of us here that know or have known your pain.
I'm glad to read that you are receiving help from therapists. That is good. I hope your parents have a change of heart shortly because living with this hurt isn't easy. One thing you have to remember for your own well being is that you didn't do this to them. Yes, telling them was what you had to do, but Hun, how they are reacting to it is their choice and they may yet come round in time. This is their doing, not yours. There is a very strong bond that parents have for their children. That could very well work through to them in time. Don't give up on hope and don't give up your dreams.
Hugs,
Laurie
