Constant fights over money. Anyone suffered the same?

My family has constant fights over money and it makes me kill myself. My mental health gets fucked up so bad I feel uncomfortable and like a looser who'll be a failure just like my family. Had to chose commerce due to lack of exposure and financial backup. I'm 20M and our financial condition is worse than ever. Im sick of this life. I don't even see any good looking at my parents fighting. It feel like even if I earn, I'll never have this happy family. It's physically and mentally suffocating. Anyone who got out of this shit pleasea tell what y'all did and how your life changed for good. Why is life always so unfair to me?
