This is a: do you experience this or is it just me.

I notice that when I'm going through episodes like I am right now, I get pressure in my head. I have low blood pressure always, and it isn't a sinus pressure. It sort of feels like my brain is too big for my skull, but mostly like my brain is pushing forward on my forehead. It only happens when I'm having episodes of depression or mania or both.

Has anyone else noticed something like that?
