Hi , I am very sorry for the trouble you are having. It is my opinion that you should rule out any
vitamin deficiency and
thyroid dysfunction, Hb levels. They could be responsible for lack of conc, fatigue, low mood, etc. also you need to visit a psychiatrist at the earliest to rule out any depression and anxiety disorder. They can also guide you on coping skills and behavior therapy.
