Replying to Depressed slump. In life.

Im usually fairly happy, yet recently I can't find the good in anything, I am not as good of skier as I want my progression is limited by me getting hurt, Im absolutely terrified of the future (graduating high school), my lack of solid friends who are actually friends lol, even as gay as it sounds my ultimate failure with women is tearing my insides, Im a hopeless romantic who as gay as it sounds really just wants to find a girl I can fully love. How do you get out of this way of thinking.... please help before the lyrics of B.I.G's suicidal thoughts become reality! Thanks for lending an ear.
