I checked, i am not eligible for income support. i didnt apply fot DLA on mental health grounds because it wasnt an issue at the time, but i didnt qualify on grounds of visual impairment. I can function with the depression (in fact several people have said im a prime example of high functioning depression, if that is indeed a thing), so i can't see me qualifying for it now on those grounds either.
Im putting in an application for council housing at the moment, in which i will mention the mental health. Im aware it probably wont come to anything, but at last i can try.
