I spent the night with a girl I liked and we had sex and had a lovely evening and I ended up spending the night. All I can think about now is how she didn’t want it, how I was bad in bed, how my breath must have smelled in the morning, how I’m too serious, how I’m boring, how it’ll never work out, how maybe I don’t want it to work out, how I’ll always be unhappy and alone. 

Wtf!! I just did something I wanted to do, why can I just enjoy it for what it is? I can hardly tell what’s real. Anyone have advice? I feel painfully insecure and unhappy
