I relate. I think that I make it more stressful for myself because I think that I will miss out if I don't go and then that makes the social thing more important, which makes me feel more stressed, so I go, but I'm stressed and I feel a lot of pressure to make this work because i don't go out very often and this is one of my only rare opportunities to make connections with people or to meet a guy that might like me and who I could date.
I think that we view social things as functional whereas others just go for fun and enjoy meeting new people. The fact that they make connections out of it and meet new friends is just a nice by product for them, whereas for me it's the goal of going out.
