You'll be alright man. Things happen for a reason, even if you can't understand it. I went thru a couple of relationships when I was younger. I thought the girl was the perfect one for me yada yada. I think everyone goes thru that. At the time I was depressed and shit. But you know what.. it worked out. I met my fiance who is 10 times better than any other gf I ever had. I look back now, and wonder why I was even upset.

As far as friends. If they are true friends you could pick back up where you left off. I have a couple friends I hardly ever see or talk to. But if I needed them all I have to is call, and they will be there. I know I can count on them more so then friends I talk to every week. The best medicine for you right now is to stay busy. Try to make some new friends, hangout with family, do something for yourself.
