It looks as if your parents did you an injustice by allowing you to stay with them. As a result of that, look at yourself and what you have become. At the same time, they are under no obligation to support you. You would have had every opportunity to get higher education, couselling(you sure need it) and least a litte minimum wage job.Your parents gave you a leg up, now it is time for you to walk. How dare you expect people in their 70s to carry you around like you are a baby.? You are middle aged and you should be helping them, but you are not even able to help yourself. I don't feel sorry for you or your heart condition. There are people older than you who. have heart conditions they keep going despite their limitations, so why can't you? No, you cannot sue your parents, that is their house, and if they don't want you in it, then you need to get out. You mention that "it was a horrible house" Was somebody holding you captive to stay there? There is a saying "if you get that way, it is your parents fault" BUT, if you choose to stay that way "it is your fault" You sound as if you have some sort of mental sickness(I don't mean it in a derogatory way) You have no desire to better yourself and that does not sound to me like a mentally healthy person. You need professional help. If this is not what you want to hear, then don't come on this site because the people who are answering your question are not professionals including myself) but it is my guess that even a healthcare professional would not tell what you want to hear. I have read the comments and noone is supporting you on this....Take the hint!
