What is the most effective way to stop bullying or cope with it? I am not asking about a fighting solution, since fighting gets you in trouble and is generally impossible to achieve 100% of the time.

I am bullied a lot, in a lot of ways, from yelling, to mocking, to spam/abusive texts/emails/calls, to physical hits and sexual comments. I want to not be bullied anymore, or at least be able to cope with it. I have been bullied for 3 years now, and I've had enough. What do I do?
