Did your abusive parents continually imply or say outright, that you're a burden not only on them, but also on all other people you interact with?
I had my parents warn me every time I was leaving the house that I was a nuisance and to not allow other people to 'feed me' because then I would be eating somebody else's food. There was a few times where I accepted a ride from my friend's parents, because I didn't dare to ask my own parents, and when they found out, they were outraged, furious and went on this big tirade about how I owe them gas money, how I spent resources that weren't mine, and was now in debt to those people, and they, my parents now had to go and make up for that debt (for the friend's parents, it was a 3 minute detour to pick me up, they were already driving their own kid).
I was discouraged from going anywhere because of how big of a burden I was on those people, and if I wanted to go to a friend's house, they would get mad and ask 'why do you have to go there, aren't we good enough for you', it was mind-boggling.
However it did force me, as a child, to continually believe I have to be extremely useful; at every house I went, I made a gift for them so they wouldn't be mad at me, and to pay my dues that I owe them for being at their place. I also didn't dare to ask for food or drinks anywhere because I believed that would make me a burden and put me in debt, and rides were considered basically unrepayable, and I had to depend on my parents for them, who would use them for blackmail every time. (you have to do whatever I say for 2 weeks, if you want that 15 minutes ride to the train station).
I only realized recently that they actively worked on making me feel despised and burdensome in every place I ever went, not only at my own home, and that it's the reason I never visit other people's houses anymore, and stick to myself in fear of being unwelcome.
