I am sympathetic, I understand how frustrating it is to be interested in women that don't want you. We have tried working together on this, but you seem to still be struggling. Have you ever considered that women aren't meant for you? To give yourself a little hope again and feel better about yourself maybe you try something new? It could be pretty easy for you, you can ease your way into this idea. Hear me out!
You have tried with women with no success, women do not want to be with you. To make things better for you and to make yourself feel less lonely maybe you see if men would want you. There are a lot of people out there, it won't be a woman, but maybe a man will!
This is going to be difficult, but I am here to help! I want to help ease you in. It would be so much better for you to start with a a trans female, you will sort of meet in the middle and have the best of both worlds. Once you have dipped your toes in and realized that the water was fine you can jump all of the way in. You will feel so much better and definitely less lonely. Just be honest, women do not want you but there are definitely alternatives.
