You're right in that it isn't uncommon at all. And it's not really something limited to trans folks, honestly. I am keeping everything crossed for you that you get someone who is there to listen to you above all. Because I think that's kind of what you need more than anything. You deserve a break, sweetie.
I just want to add, though... I am not a professional but I can always listen, and know a bit of what you're going through. And it's always free. My email is in my profile, Charlotte, if I'm not here. If you ever need someone to talk to that you don't feel you have, at any time. I don't judge.
*big hugs*
I am hoping this works out well for you, sweetie. <3 Because I see a really beautiful lady who gives everything of herself to those around her and often feels trapped in a prison when it comes to herself. I hope they can help you find the key. <3
