Hello my names alice and im 16 years old, for the past 3 and a half weeks, ive been feeling very sick but only have been sick once, i get dizzy all the time and slight pains in my skull, roughly about 6-10 times a day.. when i first started feeling sick i thought nothing of it, but now, in this last week ive been feeling rough, depressed, angry all the time, my brain feels like its going to explode,my hands and legs go numb sometimes and i feel really cold. im so confused i have no idea what this could be but im scared and need some advice?
