I understand you are trying to survive , but you don’t need to sell yourself . You need to do everything you can to learn independence. Move into a new place, with roommates, it would help you . It might not be the ritz , but you’ll feel free , and you won’t be a slave . And if you can , try looking into other jobs .

It’s not really fair to use someone for their money, even if they don’t seem to care ,

I hope you can learn to stand on your own two feet
