Why is my life like that?

I keep getting in fights with my family without any reason they just feel like it they see me as the family retard and anything I say they say I’m crazy and in the other hand if any of my younger brothers say the same thing to them they treat him like the smartest person in the world you know what? I’m done with them I’ll steal my documents and some cash and run away they are the crazy ones if they think I’ll stay with them you know what I’m running away from Kuwait I’m 20 years old and still living like this WWIII is about to start and I’m still over here like a loser that’s unfair I want to be normal like anyone else I want to have my own life and control it how ever I want
