I'm a teen too, and I dealt with it on my own because I was too scared to tell anyone. I got through it, but I still mess up sometimes. You feel a lot stronger and prouder afterwards, but it's lonely. I ended up becoming more and more defensive until I felt like I couldn't talk to anyone, and bottled it all up (I still do). Having a support system is so much better, having actual people to talk to is so much better.

Talk to your parents. You may not want to now, but it's what's best in the long run. Tell me how it goes from there.
