Over barring parents.....

Ch
Oh boy where do I begin... I'll just summarize it all. I am 19 almoat 20. I live in a house with my dad 2 brothers and stepmother who is 15 years younger than my dad.... well my dad is constantly belittling me and pointing out my weight problem... and my step mom is always cussing at me. I want to move out when I get the funds but talking to my parents is impossible. I've tried last year. What should I do... I am always respectful and honest, but I feel like I can't do anything right....
