History repeats

So, when people say history repeats its self...I always thought that it meant history its self.  Not in your own personal life, but like fashion comes up again, these problems will happen again like war stuff...  I never thought it meant you would fall in the same traps, and repeat your own history.  I found out today that I have lost my friends...once again.  I haven't really seen them since we returned to college on Sunday, only because I'm trying to keep up with school and clubs.  I have talked to them some but not really hung out a whole lot.  Today I had some free time so I went to hang out and see if maybe they wanted to go eat or something and I walked in on them talking about going out to eat tonight and possibly going bowling.  When I came in someone asked if I had my car here.  When I said yes she asked if I would mind them using my car. Not if I wanted to come with, but if they could use my car...It seems like every time they want me to hang out it's so they have more cars, or so they can get away from what ever or complain.  Maybe I'm over reacting but I feel like I'm losing people left and right.  This has happened in junior high, high school, and now college? I don't know how many times I can continue to be hurt and continue to lose friends.  Part of me just wants to give up and stop trying to make friends. I know I have some good friends, but how long till they leave? How long until they forget about me?
