feels like my brain is shutting down and dying? Long story short i’ve started getting daily headaches but sometimes i feel a weird sensation in my brain. i feel like it’s slowly shutting/fading away and it makes me very scared. it hurts and i feel maybe a stabbing feeling in the middle of my brain along with the headaches and eyestrain.  and a lot of times i feel like my eyes want to roll in the back of my head. just anxiety? cluster headaches?, migraines?, brain tumor? seizure? :(
