This happened to me in primary and secondary school, then I worked on personal growth, read some books etc, went to drama courses, at the University I got friends who were even more shy than me (or so they said), they didn't look shy to me lol, or we were sort of similar, artsy/creative and interested in similar things, or there was a 'happy medium'... (some give and take, both people talking..)
I actually get along better with people who aren't too extroverted...

or can be both introverted/extroverted, like me... And need some peacful time too, yup...
You can learn how to make friends

The idea is to smile and be friendly, say hi, comment on any things you like, find people with common interests (eg eco or whatever else you are interested in) and start talking a bit, and things may happen even without trying... There are tips for making friends online and in books... It's easier when you make friends with one person, cause then you can make friends through them too...

Hey, maybe you can start an 'eco team' at work, and see who signs up? (if you don't have that already?) Or help a non-profit? Good people can be drawn to humanitarian or artsy/crafty pursuits too... And it can give you an 'excuse' to talk to people, if you go around collecting volunteers or contributions or such?
