Is this normal, or am i going crazy?

ok i have alot of problems, and dnt wanna go to the docs just yet, so anyway everytime i laydown to go to sleep my head hits the pillow, if im laying there for a short while, when i lift my head up again i get this strikingly painfull strain on foreback right-side of my head..? i have never had this feeling before, and this is only one of many of problems that just keep stacking on, i also feel like i have lost my sense of self, my actions are like foreign to me, i wake up and i feel like i wanna get up , but i lay there motionless staring at the ceiling. i have lost a sense of well-bieng and self awarness, when i eat, my mouth is of course is chewing the food but i have to obsessibly over-control on how i chew the food and swallowing it! this is so bloody unfair, how much **** can i handle.. but i think school has alot to do with this.. and i should add that this year in school i have alot of cles well mainly all of them i am completely isolated , no-one seems to give a **** if im sitting by nyself, to them its like it all fits well, everything works well when everyone has friends to talk to, accompany them, and have a sense of well bieng, me on the other hand should not have to be the opposite, before all this crap, i was a totally different person, sure i was still quiet before, and i will always will be. but now i feel like my true self is inside me that i am trying to show, but on the outside my actions are and emotions/expressions are just something that does not feel right for me.. so now i am stuck with this feeling physically n emotionally... if anyone can solve this problem then i will be forever gratefull, and thank you soo much..
