A hotline can be good but if I understand you right you have been living in a severe depression for a year with basically zero self care or exercise. This is NOT judging you. Your body needs as much help as your mind at this point. I know it would be extremely embarrassing to look for real life help, but it might turn your life around! Just think about it. You might have a future where you can take care of yourself and where you are not sad to the bone. Please don't just throw that idea away just because it feels scary.
