Hi , I am having lack of focus, problem making simple decisions, feeling lethargic always, lack of interest in work and other day to day activities, Not  enthusiastic anymore for the things I used to be before. Lazy and sleepy , problem recollecting things which I just heard, usually problems with main key points that I just hear , I tend to forget. feeling low and sad for small things and very low self confidence. Giving up on things and not trying. Can you tell me how do I get back to normal lifestyle
