Am I the problem?

Hello Reddit. I'm a 26 year old female. I am dealing with a lot of mental problems. I am having family issues. I was born in a toxic family who drinks a lot. (My mother barely does drink) Am I the main problem being in a toxic alcoholic household where the sister is a drunk and abusive who would say crap about me to my father including 2nd sister, youngest sister and mother and say that im worthless, lazy and don't do anything, but get fat. I do everything and help out. I make sure everything is perfect for everyone, but no one appreciates the work I do. The more they say, i don't do anything. The more i want to kill myself because of them. I don't have the strength to keep going. I think I survived long enough since middle school, but my best friend (male) keeps supporting me.
