I came from a horrible household, my mother constantly told me to keep quiet and not ask of my opinion.

I moved in with my father and his wife a bit back. I am use to having to work things myself and just ignoring other people, not having help and always having to be silent.

Whenever my step mother tries to help, or even suggest anything. It's like all my walls decide to try to attack and everything out my mouth is "Whatever, I just hate it, nvm, im fine, i'll fix it" then she gets angry cause im not discussing it and just immediately try to fix it instead of talking. I get im still trying to get use to a parent actually rasing me instead of myself trying to raise my siblings. She says it"s attitude and I guess it sounds like that when it come out, but I just have a hard time explaining anything, so I just instantly try to walk off and fix whatever she tells me to

Then me and my brothers bicker alot, he tries to one up me, in anything. If I say I played a game for a time, he says he plays longer. Hell he tries to one up me in truama. Out of the blue he will just mentiom "I been hungrier than you, we once went without food for 3 days" and im just sitting there confused. Or it will go "I been beaten worse than you" and it gets frusterating and I snap back at him. Then WE get in trouble when he is the one trying to use my past against me.

I don't know what else to do except to just stay silent to everyone. I snap and get defensive too fast and I know it but it's just to hard to put them down.
