Feeling weird :(

Anybody get jittery nerves/feeling like cant focus or walk or out of touch with reality? Just started today. Not feeling anxious and am completely scared thinking its a serious illness, had random head pressure since getting hair done at salon on 19 sometimes hurts to comb or brush my hair, since then. i had a panic attack at work today and started crying. Dropped things as well and people called me neevous and right now i am completely afraid to fall asleep. My head pressure is now gone since my mind is off of it but feeling small ticks and pains. I feel tired from lack of sleep, and shaky. And i am scared to fall asleep. If i dont feel anxious what could it be? 

On april 19th

Also pain seems to intensify when i am thinking, i no longer feel heavy head or ear pressures just jittery nerves and like a nervous walk or clumsy i am freaking out

Also breaking out in hives or something

Do you take meds ?

No meds, feel shaky or jitttery.. tired as well
