everything is wrong

I am 18 about to graduate high school. I have been accepted to 2 colleges and I picked the one closest to home (which is still 5 hours away) and I am not excited at all. everyone says they are but I just cant get excited. I feel like nothing is going right especially bc the guy I thought I was going to marry ended things cold fucking Turkey (we were actually in a good relationship so idkwtf). Plus, anytime I try to talk about all the things making me upset and giving me bad thoughts, my best friend thinks it's a competition? she 8nsays "well I'm really sad too, you have a better life". umm shouldn't she just let me get things off my chest? I don't really care if no one responds to this I just was tired of keeping it bottled up. if you are going to respond though, tell me things you do to calm yourself down. any words would help I'm sure.
