Nothing ever brings me pleasure in life

No matter how much i try to find myself something to pass time with,i just cant find pleasure in everything,and i mean everything.I have tried chess,exercise,reading books,nuclear physics,stock market...none of these worked for me.I lack enthusiasm about everything,my dopamine levels are somewhere far below zero,therefore i only spend my time rotting in bed all day and scrolling useless shit on yt and tiktok and suffering.Im so fucking frustrated
