I improved a lot after meeting my first (ex) girlfriend through a dating app. She liked going out and one of the places we'd go was a Pub near her parent's house with live music. Initially I felt ackward there. After going there a few times and specially when the band was playing songs I liked (and with a little help from good beer) I started loosening up. I'm not really sure why but from that point forward I started not really carying anymore about "other people looking at me" when I'm enjoying the moment and having fun. It's like I flippled the "I don't care" switch on.
