I hate my step brother.?

People who are feeling confident and secure and have self respect don't feel a need to call bully anyone. Try to record any such conversations with him, especially threats. Keep copies - give some to friends to look after.

At fifteen your parents are responsible for your safety and welfare, so talk to them about this. Have you any grandparents you can talk to? Or call 1-800-4ACHILD if in the U.S.A., or Childline (0800 1111) in the U.K. No doubt other countries have similar free phone lines. Canada is 1-800-668-6868.

Can you join a self defence or martial arts class (without telling him)?

Bullies want attention. If people allow them to get their way through fear (the ultimate emotional reaction) they are succeeding and will continue. One way to combat verbal bullying is not to ignore them completely as this shows that they are getting to you, but demonstrate that you have heard the remark or whatever with a glance, dismissive wave or brief response (""oh yes", or similar) end THEN ignore them. Why should you care what such a pathetic person thinks of you? Alternatively, or in addition, try to use some humour (U.K. spellings!). It need not be mocking humour, but some light-hearted banter can often diffuse situations.

Put on an imaginary suit of golden armour, and visualise the unkind remarks (or those you perceive to be unkind - be very careful not to imagine a slight when none is intended) as arrows, harmlessly bouncing off your armour and falling to the ground.

Good luck in your difficult situation.

You need to have a family sit down talk! Or you need to pull you dad aside and ask him for help! Look, He (your dad) put you in this situation and he should make this a home for not only his new wife and her brat but he needs to make this a safe happy home for you! Do you have Grandparents or a mother you could live with? I wish you will have a talk with your dad and let us know what he will do about your situation! IMO, the little house bully will always pick on you until you stand up to him! Does not matter if he beats you up if you fight back and get your "licks" in also. When a bully knows he will have a fight on his hands, the bullies will look for easier victims.
