Hey there, you’re going through a lot and I can relate to your story. I grew up in a narcissistic household, my sister was the golden child and I also have a brother. Parents paid for both for both my siblings higher education but I guess I was too much of a piece of shit and they refused to pay for mine. Had to gtfo at 18 and work 3 jobs and take out loans and credit cards to pay for school.

This situation has been bad for you and will continue to be bad if you don’t get some help. A resource I found that’s good is r/raisedbynarcissists on reddit. If you can get counseling, please reach out to someone who can help you with this.
