Hi hun.. I jus turned 22 in Oct, so not much older than you. I'm married, also have a little boy and a little girl on the way and YES, I know exactly what you mean. Unfortunately, I have no friends since I had my son because we just weren't on the same page anymore, I was a mummy, they were still in college etc! - Does make you feel slightly old, but like you said, don't regret it!
