It is weird, cause sometimes it's in my head, like, literally in my head, I can feel it, sorrounding my cheeks from the sides of my head, warm, pulsing, hurting my eyes, making my veins swell, presing my jaw...

Comparing could be the reason... but what if that's not it??

What is it then?

When?

What do I need?
