Parents that we can’t choose

Just wondering if anyone grew up in a not so conducive environment? Growing up my father always like to throw things around the house whenever he gets angry. I never knew this was wrong until much later. My mum wld always tolerate him and ask us not to make him angry. But now that I have a toddler in the same household, he doesn’t throw things but he likes to slam door and shout loudly. My mum on the other hand likes to criticise us whatever we do, calling us stupid, fat, poor etc. Never receive any compliments from them. I feel bad for my toddler because I wonder how much of this he’s taking in. We still have at least 2 more years to stay with them before my new flat arrives. Can’t wait to move out.
