I hate how people are when you complain about being fat/raised in an unhealthy household

My parents didn't raise me with healthy eating habits. My mom's side struggled with obesity and my dad didn't give a fuck and fed me junk food starting as a literal baby lol. I was also BLAMED FOR MY OWN WEIGHT ISSUES by my parents as a literal child as well. If I had said all of this and then said "yeah my parents actions contributed to me having anorexia" people would understand completely. HOWEVER because I'm overweight the response is always "you need to stop blaming your parents and grow tf up" Like yeah It's really fucking hard to stop binging, it's really fucking hard to just eat healthy when you've only known one  thing your entire life. 

I'm aware I'm an adult now. I also don't think I'm wrong for resenting them for not raising me in a healthy environment lmaoo.
