How can I stop being a bully?

Just let people be. It's understandable that you're probably going through troubled times yourself, but that's absolutely no excuse to take it out on other people. If you don't like something about somebody, just leave them be. Nobody deserves to be treated badly just because somebody else wants a "joke" on somebody else's behalf.

One of the first steps would be maybe you could look what causes you to be a bully? Usually if someone develops this kind of behavior something in their home is wrong.

Stop being a bully as you need to remember what it is like to be the other person and just leave them alone.

Ask people who bully you very politely to stop bullying. Try to ignore them in an ideal way. If nothing is working out, then get help from your guardians.

Bullying people makes you feel empowered, so there is a reason why people do it, often they do it in groups. That is a horrible thing to do. Remind yourself of how YOU want to be treated by others and make active choices not to be a bully. It will cause the other person so much pain and you wish you weren't in their shoes. So don't make them wear those shoes.

First of all, imagine being on the other person place. Second, imagine a person you love was bullied. Reflect on what it made you feel. Wanting to stop is a big step. If there is space for it try getting to know the other person.

Treat every person in your life how you would want to be treated in their skin. That way your bullies would take a look at you and do the same.

Try to gain a better perspective on yourself and try to have a basic understanding of why you feel like a bully. Also, try to calm yourself and think before you speak, if you think it could hurt someones feelings try not to say it.

Being a bully originates in fear and intimidation. The usual culprit in this behavior is low self esteem. Ask yourself why you feel so much threatened by others, what you are afraid of in relationships and what you really want from your peers. The work to be done goes beyond these questions, but they are a good place to start. I recommend you connect to a listener and try to get in touch with your feelings an insecurities.

That's a good question! I think that you're already off to a great start in recognizing your behavior and wanting to change it. A good place to start is by reading some books on self-love and portraying the person that you want to be.
