I hav a serious problem....Any psychiatrists or intelligent help is needed!!!?

I m 17...male...It started last summer. not suddenly but gradually. I used to be a jolly person but since then I have changed. The problem is that I can't define it.I'll tell you the symptoms. I like stayin alone. I like to stay in darkness. I feel relaxed in darkness. I hate light. Hours p b4 I realize that m in the corner of my room sittin alone doin nothin...just like it. There is a jungle n a stream behind our colony. Evry1 is afraid to go there...bt I like to go there n i did.!!!!!!! I went there n sat in a corner whn my papa arrived.. shook me...scolded me n took me home...!!! I used to get gud grades bt now i fail in every term n i dnt regret it....!!!! I accept that I am a loser n think its O.K.!!!! everyone says that m gud lukin bt still no grl wants to b my gf....I hav seen dorks n goofs with gfs....!!!! Also I do alot of day dreaming....all the time..!!! I like to stay unclean n i masturbate a lot. I like to go to jail n i like to hurt myself Now comes the main part...Last week I locked myself in a room n the room was shaking n there came a figure(of human being) cd nt c its face...it was nt an illusion. It was real!!! Bcoz the light striked at the body n was reflected back at me otherwise i cd nt c it.....I had fever for 1 week n i had the same dream for 5 days that m havin with a spirit n wild dogs r biting me. Then i c myself in a sea...on 1 side there r whales n on other sharks....!!!! my question is gettin long...since i live in countryside there is no nearby psychiatrist....Plz help me...I dnt thnk its a problm bt my parents do!!!
