My best friend of eight years has recently moved out for the first time, and I feel that she is growing up without me. We don't laugh at the same jokes we used to, and she takes on several classes plus work and is trying to find a second job, and I can only handle one job and am still living with my parents. She can hardly find time in my schedule to see me, but she hangs out with certain friends quite often. She is my only friend that I can confide to, but the other day when we were out eating dinner, she told me we have nothing in common anymore.

I don't know what to do, it doesn't feel like we're best friends anymore and I feel like we are going to see each other less and less until we never speak anymore. I don't know how to rekindle a friendship, when clearly I am the one who is lagging behind in the maturity level, and it's not that I'm immature, it's just that I don't have as much experience as she does. How do I rekindle a friendship?
