That's exactly how I feel sometimes. I have a lot of days (probably most days) where my brain is just in this fog that never clears up. I could be up for 12+ hours and still feel like I just woke up. It makes it incredibly difficult for me to focus on things, and I won't even bother with surveys or HITs with a lot of instructions because I have like no reading comprehension at all. It's very infuriating when I'm really hurting for money and nothing I can do will snap me out of it. Seeing a lot of high earnings posts on days where I'm really struggling with that can affect me very negatively, so I have to try to tune them out as much as I can.I also find it really demotivating when I'm on a bad streak, just makes me feel worse for not being good enough. But obviously other people feel the opposite
