Oh god I can't fucking go anywhere else with this, maybe I should hire a shrink, but for now here is all I have

So this supposedly 18yo from tinder, we went out, I swear to god I couldn't tell it was a man, I thought her hands were a bit big but I she was kinda tall so I didn't think much of it

'It' was young, didn't look like a dude. Oh my god I kissed a dude.

The next day I get a text saying he's a fucking trans girl, I want to put a bullet in my head

What the fuck do I do
