I really need some help Know anything out pyscology or teenage emotions

A few months ago, one of my closest friends turned agaisnst me, she swore at me, blanked me, and back chatted. Normally, this wouldn't have bothered me, I would just get on with life and wait for things to settle down. But it did bother me, a lot. It was at the back of my mind nearly all the time, I went completly unproportional and often cried myself to sleep. I would cry in lessons at school. I had no idea what was happening to me. Eventually, after a few weeks, my friend made up with me.

I was fine then, for a couple of days, when I suddenly, out of the blue, became completly governed by the fact that I didn't have a boyfriend, something that had never bothered me before.

I eventually got over that, but another thing came along and that one thing controls me for ages.

Even today, I was sworn at in hockey becuase I accidently hurt a girl. I came home in tears and now feel awfull because of it.

Please tell me what is going on and how to stop this happening.

Believe, me I know. I am going thru the same thing myself. My solution: find friends that are super good to me, and hang out with them. I have a group of guy friends that is just amazing. And I know that in that group, I have a future bf. But somehow that doesn't cross my mind when i'm with the 3 of them. What i'm sayin is, find some people that are great for you. When you're with them, you won't even think about a bf. Not to mention your other problems.
