As others mentioned i would seek professional advice. But here's my anecdotal advice, whenever i feel self pity and overwhelmed to the level where i don't know where to start, i try to get back to basics and focus on small picture stuff that are within my control. Anything that you'd be happy with doing for the day, that depends on only yourself and not other's approval. Start with trying to improve your mental health and mood, wether its a small level of exercise, better diet, saying yes to any social occasion, change of scenery ... Once my mental outlook improves, the rest of my approach to life improves. P.S the fact that you took steps to reach out for help is a good sign
