how to stand up for yourself

STEPS
Find out what is wrong and why you want to stand up for yourself. If it is a bully or an abusive person then read on to the second step.
Sit down and think about the problem, he/she could be making fun of you or spreading rumors. Whatever the case think about the seriousness about the problem.
Anger yourself! As foolish as it sounds it is a good motivation to get you to get over your fear of speaking out for yourself. Do not let anything back! However don't go and strangle the person for pity's sake. Punch a pillow if you have to, think about what the person did to you!
Confront the person. If you need motivation think about step 3. Walk up angrily and tell, not ask, the person to stop whatever he is doing. If he/she has friends he/she will most likely turn to them and laugh. Then get Chest-to-chest touching and get in the persons face and say it again only louder and with more anger, read next step..
Be prepared to feel half peeved off and scared to death and to realize that his/her response from step four will be to push you away. Do not become violent back. Just respond with sensible words. He/she will taunt you but you must remain calm and angered. Don't just be angered, look angered as well; clench a fist but avoid violence.
Start yelling at this point. Demand that he/she stop the problem. This will attract attention that he/she will not like so very much. It will also involve other people as if they expect a fight and are separating you two. Get louder and louder until he/she backs off. If this does not work then let your gut feelings guide you on what to do next, the feeling you will face will not listen to a .
