Head throbbing and axiety attacks

i get a head throbbing sharp pain that feels like my whole brain is moving inside my skull? and it makes me feel dizzy and stressed.. i have had for the past few weeks bad axiety attacks in my sleep and everytime ive woken up ive been crying or having troubles breathing or even sometimes shouting out to people near me, could you please tell me whats going on with my body? as i am only a teenager who's worried thanks
