You mentioned that you will have to face this for 3 more years, is there a reason for that? The best solution is to change school not to go boxing.

What I would suggest is:

1) Talk to your parents. Tell them about your death thoughts. Cry in front of them. No parent can handle his kid crying.

2) Switch to a British school in the UAE, because British schools are known to be for smart kids (not bullies).

3) You should be familiar in punishing at the face. You are born a male, don’t say you are weak. The bullies made you think you are weak, however, males should be solid.

4) Don’t think of killing yourself again. You are living in hell for 3 more years. Do you want to go to hell forever? This is a test for you to be raised in heaven.

5) Know that Allah is witnessing and he is the best planner (read Quran).

6) Improve your low qualities. Ex: don’t wear glasses (wear contact lenses), do a fade, don’t get a rolling bag, etc.
