Not knowing what's wrong is a stress factor and you mentioned that you're not taking naps. From my experience it's always been me trying to push myself to the limit, ignoring the simplicity of maintaining a "suitable" diet.

As I write this it's only 5pm and I'm in the exact opposite of what you are experiencing today. In my case, I'm to hypo to even talk with my family. I'm saying everything that's on my mind, but I know why...I consumed 2 redbulls. I hope my point comes through clear that a doctors visit would be great as long as you're not a prescription addict seeking drugs.

Breakfast cereals are antidepressants and increase your fibre.. but you know that anyways [emoji767]
