I suggest you find a mildly stimulating activity that engages your brain just enough so you do not get stuck with your mind ruminating on your struggles/symptoms and use it to zone out for a bit.

Forced rest with your mind struggling is not good rest. If you have music or a video that allows you to rest your thinking.

If you start to struggle, loose focus, etc. Take a break.

Studies show that short breaks throughout the day are better than one longer break.
