I don't think "semi-attractive" is the word, but I've been in relationships before, so I'm bearable I guess?
I'm in my 20s and I definitely wouldn't go for a relationship again. I learned that healthy people with a goal in life and good intentions for a relationship aren't interested in someone like me. I don't fit into the life of someone who's actually progressing towards a goal when I'm not. I'm not exactly capable of holding a healthy relationship either with the wreck of my mental health, so it's for the best.
