Well, when I was your age I was pretty stressed out and depressed as well, though never had a relationship... never had that opportunity until far later. That happened only after things started to turn around, right when I got out of high school and turned to God for help... I mean, we're only human and always are imperfect, so if you are feeling down and need help why not turn to the creator for help? Jesus is loving and patient, and there is a spiritual side to all of us that needs to grow through a relationship with him, so I'd suggest finding a church if you haven't and going to counseling altogether.
Get the aid you need for mental, spiritual and emotional growth, then seek to learn these aspects of life while growing in tandem with Jesus in a personal relationship of father-daughter, and take life a day at a time. Godspeed.
