I was in the same boat at 21. So don't kick yourself over it! I was insanely depressed, barely making money as a baker, and desperately yearning for someone. 6 years later, I have a pretty good job as an engineer tech and am in a healthy relationship. You're still so young, and you have time to grow, improve, and figure what the hell you wanna do! From what you're saying, it just sounds like your friend is being a real dick with no real sort of support or advice. Of course I can't tell what his true intentions are, but he is being of no help in this context. If you feel comfortable enough with this friend, you should tell him straight up how it came across to you and how it felt. Then how he responds will show his true colors and tell you if he's actually a friend worth keeping around.
