You're making me laugh.
Ladies, 22 is not old. I'm 23 (will be 24 in september) and I don't feel old.
At 22 you should still be going out and having a blast. I was still in school at 22 (althought I didn't start university till I was 19 thanks to OAC)
These are the times you should be out having adventures. You don't have tons of responsibility, enjoy it while you can. I think you should be lucky you can still hang with your younger friends/sisters, but mature enough to enjoy time spent with older friends.
I persoanlly think 22 is too young to get married and they're going to miss out on a lot of things (but to each their own I guess).
You're only as young as you feel, so start feeling young
ETA: I feel like I just wrote this post in Earpspeak. I hope you all understand what I was trying to say because I don't think I do
