I don't know you or what you're going through, but even if that's true, that's ok. Your value isn't determined by your contribution to anything else. The point of revolution is to provide comfort and dignity to the powerless, including those incapable of laboring. You don't need to justify your existence.

edit I say this as a probably-autistic mentally ill NEET shut-in lol. Even after revolution when I might be able to work without agony, I'm not sure how useful I'll be.
