I guarantee that poor physical health contributes to depression and mood disorders. It can go the other way too, which can create a nasty cycle.
I already posted something to this effect in another thread where you posted, but I’ll say it again. You might want to consider an exercise program, which in addition to helping with your physical health might boost your confidence and help you become independent. Do you currently exercise? If so, what do you do and how long and how often?
