I'm struggling with some condition which is making me feel alternately tired and hyper. My blood sugar has been tested and is ok (as far as I know). I do notice I sometimes feel different after meals but largely it almost seems arbitary.
When I feel tired it's not a sleepy tiredness, it's more like my mind and body is just drained and I can barely really stand up or carry out basic tasks. I just want to lie down and can't really do anything.
When I'm up I feel super tense (mainly in the shoulders), euphoric and I have strong palpitations, I feel like I can't relax at all and just have to do stuff (I'm kinda up now).
I don't really have a problem with anxiety as such but haven't been able to relax in ages. Could this potentially be a sign of something like diabetes or insulin resistance or would there be more recognisable symptoms?
On that note, if it's not this, any idea what it might be?
