Is bullying ok?

Of course it's not okay. Now, have you told anyone in person about what's happening to you? Have you tried to do anything about the situation you're in? Because the change you need to have happen will probably, at least in part, need to be precipitated by you.

First how old are you.

If you're an adult tell your work supervisor. If you're a child tell your teacher, parents, principal, and friends.

It is not your fault. I'm a substitute teacher, an author and former self-defense instructor. You are just fine. The weak cowardly bully is the one with the problem.
