I get all obsessed with someone so easily that I don't want to talk to someone else on an app, and start feeling good for the first time in a while, chat with him for a while, later I get anxious that I fucked everything up or feel invalidated, and ultimately it doesn't work out. (I've had like real life dates with guys I met online before, but it more like showed how we are incompatible.)

And from then it's just the ultimate black hole of depression. I'm scared of what will happen when it strikes again.

Edit: Also I double text sometimes, when I later think a message of mine is bad, I don't do it to get a reply faster, but it might be annoying? Still feels better than to let something stand which could annoy someone more I think.
