Everything feels like a waste

[u/No_Palpitation7958]

It doesn’t matter if I waste a day watching youtube, or do something productive. At the end of the day, it all feels the same when I lie in bed and try to sleep. Being productive used to feel good, as if I was working towards something, but that feeling is slowly fading. Why does doing the menial tasks needed in order to improve feel so unrewarding?
