I'm going to get in a fight with my step father
Are you serious?  Why are you planning to fight with your step father?
Because he seldom at home and is seldom there for me.
There is probably a good reason why he is barely home. Some people have to work extra hours and can't be available all the time. Try talking to him calmly about this when he has time.
I don't care and I'm going to hit him if he doesn't pay attention to me.  At least it will make me feel better.
I understand that your stepfather is not giving you the support and the attention that you deserve, however, violence will not solve anything here.  Next time you see him, let him know that he is ignoring you, but do it in a setting where your mother is also present, so that she can keep things from getting out of hand.
