Living in a dysfunctional family (contains tmi)

I grew up in a dysfunctional family and in our country, there are no “rules” to leave home at 18 and etc. We live at our parents house until we’re married and then live with our in laws. So we can’t leave our home either. One thing our Parents do not understand is that they created this dysfunctional family and we learned from them all the negative stuff which affected our mental health. But then again they don’t even believe in mental health. So we’re not “allowed” or are “frowned upon” to get professional help/therapy. Here’s an example of my daily life : so I’ve been feeling suffocated in my own home forever, since childhood but if I react to it, then it is my fault and I’m overreacting. My parents…..they fight like all the time and when me & my sibling try to stop them, they attack us (not physically, we’ll just once physically) and there’s no stopping them. If I ever tell them I need mental help, they say “just focus on your studies, what else do you need to be stressed about? You’re too young to be having stressful situations. I have worse problems, my colleagues did this, they did that, I had to suffer worse and I didn’t get any help, I’m doing just fine, I’m keeping everything to myself. What is therapy? You should just get some slaps and you’ll snap back to reality “. So basically this is how I grew up and still living like this!…
