my dad one day had a really bad back pain, and couldnt go to work, i feel bad for him, but he has been treatin me like shit. screaming at the top of his lungs if i did the simpliest thing wrong. and theres nothing i can do about it, if i was to fight back, he would yell at me more. he doesnt even understand how its making me feel and its making everyday since he has been home misserable. he tottaly brings down my self of steam. is there anything i can do??
