I've been in a constant state of having a weird head feeling since the end of January and I don't know how to deal with it. It feels like immense pressure, my head feels heavy, im dizzy, throbbing pain and ill get random moments where I get like a shooting fuzzy feeling flood my brain and it fills me with panic and the feeling of doom. I constantly worry its going to kill me and up until January this year I've never experienced it before. Also when I lay down to sleep and I'm on the verge of sleep I wake up to a sudden rush of fear and my body jolts awake like I was electrocuted, any advice or reassurance would help.
