venting and trauma dumping yayyy

ATTENTION!! this is touches a sensitive topic. sorry 

I had a horrible weekend, my parents fought and got aggressive, I always hate when they drink alcohol because it always ends bad, it's been a year and a half since they had their last fight that involved physical agression, well, they did it again this weekend, I had to stop them, just like past times, since little I've been the one to stop their fights, I remember the fights started when iI was like 9-10, it is horrible to remember my younger self crying and begging my parents to stop, and year through year it kept getting worse, they kind of solved their problem a year and a half ago, but now I have trouble sleeping when they drink, because i'm scared something will happen, any noise I hear I immediatly stand up and go look for them, now I had to revive all of that again, My mother yeled at my father, my father yelled back, they started fighting, I had to intervene, one of them slapped the other, I went in to stop them, in the proccess my arm got hurt, then they got even more aggressive luckly after begging, screaming and crying, they stopped, I separated them in different rooms and waited for them to sleep, I couldn't sleep after that, now my eyes still hurt, I'm to tired for this shit. They act like nothing happened. 

They aren't bad parents and they're not alcoholics, it has happened multiple times in 7 years, not every week, but before it was like 3-4 times per year, it's not much but still I'm tired of babysitting two 40 year olds, I really love my parents but I really wish I didn't have to live through that

any spellling mistakes, I'm sorry
