How to get parents off my back?

Ok so my mom and stepdad are like omg making me so mad right now, I mean well it is just my stepdad actually he was at work this morning and I am babysitting for the summer and he calls me to yell at me to do a bunch of crap during the day and he just...

got home and yelled at to pick stuff up around our pool and my sister doesn't do crap to help out during the day even though she doesn't have a job and then my stepdad also yelled at me to clean the counters even though I cleaned the entire kitchen today he makes me sooo mad sometimes and then he pretends nothing is wrong and tries to be all nicey nice towards me but whatever HELP NEEDED

that's normal... but not in a sense that you are insecure with your stepdad..

man thats the same way here exept its my older bro and my step dad dont work but I am always doing everything and on top of that I have to babysit my lil bro[3]everyday but I am starting to just block them out

try to write your mom a letter so that she cant interupt you when your talking and she will talk to him.communication is the key to fix that.hes suppose to be your dad not your boss.and the fact of the matter is he is not your dad so he should respect that fact not abuse itbe honest but respect them both in person and that letter dont give him a reason to yell so that when he still does it you have the truth on your side
