Anger, if used right, is a powerful tool to accomplish things. In this case, it is clear that the people that are in your life as of right now are upsetting you or at the very least don't seem to give a damn about you.

Use this anger to do something about it. Tell these people to GTFO your life and use the anger to give yourself the confidence needed to meet better people.

I can't speak for everyone, but when I'm angry, I have a higher level of confidence and I am more motivated to do things. I consider it to be far better to be angry than depressed because if you're depressed, you will have a much harder time getting out of the rut that you're in.

Embrace your anger. Just don't do anything illegal and you're good.
