I don’t know how to make friends!

I (F24) have never really felt like I belong anywhere. I always feel like I'm just a weird extra with friend groups. Even in high school I was always just a drifter between different groups and that usually had to do with whoever was interested in me at the time. My middle school years I ended up pulled out of school and I lost any real friends I had since kindergarten so going to highschool (in the same town) everyone had already created their groups, and my friends weren't my friends anymore. I ended up going to college at 16 and I couldn't make any friends there cause everyone treated me like a kid. I became a parent young and of course nobody my age wants to hang around with me cause they don't have kids and are living life and I don't blame them. I've tried making friends with people older than me who are "in the same boat" and they still look at me like I'm a kid. I guess what I'm trying to say is I have always felt like I'm too far ahead and too far behind at the same time.
