Am i crazy or what, i just dont get it?

i always liked writing when i was a kid, but somewhere in the 7th form, i gave up, because things got more serious that some childish stories. 2 year ago i became really crazy about music, and my taste in it is really strange to. When i lie in bed, i always listen to music (mostly trip-hop and anime osts :D) and i start imagining things. not things, but the whole story! Stories. The characters and everyone, mostly fantasy, fighting, no normal things :D and things i have never thought about before. I mean, i dont just lie an think what the main character will say or something, it comes itself. Mostly about what life is, about not being human and not feeling anything while killing tons of people, about the reason to live. And most of the stories are sort of dart. It's like a movies, with the main character, his personality. Then i start drawing this characters, and in became really interesting. i tried writing the first story, and liked it at first, but in the middle i stopped. I could imagine things about that same story anymore. And i gave up on writing cause i thought i was because i like wrote some secret i shouldnt have or something. In these 2 years i have imagined somewhere around 50 stories. And the characters are like my friends, and when something sad happens in my story, i cry too. I cant live without imagining things. And i was like in depression when i stopped for a while. I am addicted to it. I have a normal life, normal friends who i often quarrel with, and it makes me crazy. I always cry at night, and when i am alone i cant stop but think about things, about life, about family, mostly things that arent normal. And i cry because i want to be in one of my stories, because i think my life is boring, and no matter what happens, if i have a good job, a normal life and family when i grown up, i still wont be satisfied. it will end someday, and nothing out of ordinary will happen. I always want to be next to my characters, and i the things that interest most teenage girls here, dont interest me, though i always pretend they do. And i like reading things about hallucinations, psychology, Dissociative identity disorder, phobias , though i dont get much. I feel like i dont belong here. I think i am gong a little crazy, and there is nobody near me i can talk to about it. I feel like i am living like a robot, i do everything i am said to, and whenever i say no to people, they dont expect this from me and get really angry at me and ask me where did the old me go, because i used to be a nice kid. What is wrong with me?
