Burden is the exact word I would use too. I rely on my mom so much and the one thing that I could do was pay her rent. But then my hospital bills went up and I have a big bill from the vet and need to save up money for some dental work and so now I have to pay a reducted amount instead of the super low rent. It makes me feel about __ big even though she's been nice about it. I need help to keep my house clean. I can't cook right now so she feeds me (which is the only way I could afford most food anyway). It scares me that when she is gone my sister will feel obligated to take care of me and I don't want that at all.
