I have the most trouble at night, in the middle of the night like you're having a tough time of it sounds like. I get the weird thoughts when it's dark and quiet and there's not many good distractions. All my boogeys seem to gang up on me then.

It sounds like you're getting an okay amount of sleep, much of it being in the day and I think while you're ill/recovering that's okay? I can see how it might add to the feeling of things not being in control/"normal" but just being ill does that for me. I remember when I was out of the hospital and how topsy turvy things were for 6 months until the surgeon and I figured out all my problems and set them straight.
