Sixteen is h e l l for anyone...I'm sorry that you're going through this.

Also at sixteen, sometimes family tend to not take us seriously when we say we have a problem (at least that's the way it was for me)
So it makes it very difficult to have a real sit-down heart to heart with them.

I would say that a trusted adult at school would be your best and safest bet.
Teachers are not teachers for the salary (trust me!) they are there because they WANT to be.

I can't tell you who to go to....is there a counselor? Some school districts have a "travelling" school psychologist...google it for your district.

But just ignoring how you feel will not get you to feeling better.
