I been dealing with most it all my life but I would have to say maybe anxiety where it crippples you to the ground and you miss chances of going outside seeing people get married seeing babies be born or just being able to move out of that stricken feeling that last for hours it seems like. you just miss out on life in general...where as with depression I still can leave the house and see life just pass before me but crying while I am walking isn't in the plans some times but it does happen.but to me anxiety has crippled my life as I know
