I tried to stand up to my bully and it didn't go well, what other things can I do to cope?

First of all never hide a bully they should always be exposed don't worry about what other kids will think what other people would think specially what that bully thinks if you tried standing up and they still didn't stop tell a parent a teacher or the principal

Tell your family, any teacher or any staff in the school at all, and tell the bully to stop of course. It's not always easy to stand up to a bully, but you have to tell them to stop, then if they don't, you have to tell your family or staff in the school. But if you don't feel like doing this, you can always try getting away from the bully and getting other friends, even if its hard too get friends, you have to try atleast. But my advice isn't good advice, so you might not wanna take my advice for it.

One important thing you can do is try to avoid them as much as possible. This way they won't be able to bully you. Another option is to seek an authority figure and see if you can bring their behaviour to the attention of someone in charge. Alternatively, you can also try to document what they are doing so that you have it on record. Finally, it's very important to have time for yourself and to not focus on them. Try to schedule some time for yourself to do activities you like, and to make yourself happy and feel better.
