physical illness impacting mental health

hi all i have been in a weird manic type mood for about a month or two and i do believe i am still in said mood except i have fallen ill with a stomach flu for the last 8 days and i am hoping i start to get better soon but i am worried this is going to drag out i am not sleeping but idk if that is my mood or because i am in too much pain from my stomach or both anyway this flu has made me feel kind of irritable and emotionally exhausted and it just is leaving me very uncomfortable. i havent been able to concentrate much at all and so my uni work is falling even further behind which isnt good and i am struggling to manage basic stuff too which i suppose isnt new but it is getting worse and i just i think i thought this flu thing would be over in a few days but it is dragging on and on and on and i am running out of steam. anyway does anyone know of any good things to help self soothe because the things i have been trying arent working?
