I recently got back into looking for people and maybe even a relationship, but it's just so exhausting. I worrie about every small detail and thing I say to the point until I'm afraid of saying anything. 
My brain also thinks I annoy everyone I interact with. One different worded massage is all it takes to throw me completely off. 
But I think the worst part is realising that there are people who are interested but I manage to fuck it up because I don't know how to talk to people. 
Eventually everyone moves on which I completely understand but it still sucks
