My parents don't help me live my life.
That sounds serious. What could your parents have possibly done to make you feel that way
It's because they don't like my girlfriend. I won't let them ruin my life. They talk down to me about it and say there's no way to have a healthy relationship with them because of it.
I's sorry to hear that and it sounds like your parents are pretty toxic but you shouldn't be blaming others for your problems. They seem to just not like your girlfriend and that's their right. It's also your right to ignore that and live how you see fit.
I think it's that because of them I have just become self-loathing. I spent a lot of time with them. Anyway, I'm moving out of my parents house as soon as I can.
That might be a good idea but you need to also understand that you have to acknowledge your own faults too otherwise it won't work out. You cannot always blame other people for things not working out.
