I find it very hard too, I've had people comment on things I do or don't do to take care of myself, and I just say well I don't actually matter enough to do these things for myself. It's hard if you have people putting you down too. But you don't have to take that, tell them to be quiet or move on from them. It can be hard, especially if you feel you deserve the criticism, but you know what, you don't. You are worth something, I know it, and you should care about yourself and want the best for you. Even though I'm a big hypocrite to say that! It's easier (for me anyway) to see the worth in other people but not in myself. We have to be worth something though. I'm sorry I've no advice but I hope you might start to find it easier. Take care.
