How can I accept that I don't fit in?

I’m a 21 year old girl and all of my life I’ve never really fit in. For the longest time I gave up on friends and I was happy just hanging out with my family and with no one else. I feel like I fit in with my family, and they are my best friends. During this time I had awesome self esteem and just felt like I had so much going for me.

A little about me. I’m an introvert, and most of my family are introverts as well. I love hiking, and running. I’m not into the clubbing or bar scene that much.

Well now I’ve started a new university, and I’ve decided it’s time to make some friends. So I’ve hung out with my lab group a couple of times. They are nice and good people, but I always feel like an extra. Like I don’t belong. All they talk about is the bar and club scene, and I’ve joined them a few times, but end up feeling drained.

So I decided to get together w/ some girls from high school. They too, enjoy the clubbing and bar scene. I went with them a couple of times, but again I feel drained and like an outsider.

Lastly, I met this awesome guy who I’ve really started to like. We got coffee in a small cafe (this was perfect for me!) and got along really well. I felt like we connected, and I finally fit in with someone! He wasn’t into the normal extroverted activities and was different!! But I asked him for a second date and he never replied….

I just wish there was someone out there like me! Someone who would rather go get coffee at midnight rather than go bar hopping. Someone who could be my running buddy, or travel all over the country and hike! I feel so stupid only having my parents and siblings as friends. I love them to death but other 21 year olds have so many other friends!

Sorry this turned into more of a venting session, but I just really need some advice… Aftee hanging out with these groups of people I just end up feeling depressed. And my self esteem is suffering from it….
