Do you ever feel unstimulatable?

Do you ever feel extremely bored, but also anything you do just doesn’t do it? Unable to really focus on anything but also unable to not try and do something. Idk maybe it’s just a different flavor of overstimulation, but it kinda feels different. Also understimulation usually can be dealt with better than whatever this (what I call unstimulatable) is.

Can you relate? How do you endure this tiny piece of hell?
