Inherent in this charge of "neediness" is the idea that you have no legitimate needs. It is a way of invalidating your condition as if it were somehow less "real" than a visible or more intuitively understandable physical disorder. I chalk that attitude up to ignorance. I mean the brain is an organ just like the heart and you don't hear people disparaging people with heart conditions as "needy." Your family may not know what to do about to help you, in which case they need to know what you need is not fixing but support. If they are unwilling to try to understand then you will have to find help elsewhere. It's too bad it has to be that way.
