Help? i'm being bullied at school and teacher says im depressed?

I used to be like you in middle school. everyone picked on me because they thought it was fun and i would just react to them and thats what they wanted so they kept doing it. but when i got into highschool I just started to ignore them. and eventually they stopped. youre getting bad grades and youre depressed because these things are building up inside you. so my advice would be to just ignore them and things may get worse but eventually they'll stop. and always look for the positives.
