I think I am depressed because of my best friend, Help please!! ?

Oh wow, well first get some new friends, the fact that these girls make you feel like this means they are toxic. Once you make new friends you'l forget about these girls and you'll be totally free. How old are you? You seem young and are currently surrounded by immature peers, just tell yourself you are better then these girls and that there are other people and things to be happy about. I can't tell if you're depressed, depression is a sickness that you have to be diagnosed with, you're just stressed. Like I said, take a bath, MAKE NEW FRIENDS and hang out with your family and do activiies with them, surround yourself with positive people. If you get active chances are you'll feel happier.
