My choice of things to do also matured a lot faster than friends of mine did. I had children when I was 21, 24 and 29. They are now 19, 16, and 12. I started quilting at a young age ~30 and my friends are all older (oldest best friend is 55).
I also think it would be a good idea to try a guild. Or if you want to further your education, try taking one college course a semester. You can go to class while your children go to school. Sign up for a class at a local library or at a YMCA.
