Shiro,
Calm down. Who wants to put you hospital and what for? If you are getting severely paranoid you may need some time out. There is nothing wrong with that and no harm done, before you do some harm to yourself.
Vexing is totally correct the you were assaulted and could report it to the police. Be careful about coming out to people that you have 'feelings' for them, particularly when you are young. They may act in an immature way as this boy did. A proper response would be to tell you he wasn't interested, and that's how emotionally mature people should act. But it sometimes difficult. I really don't want you to get hurt and your posts are displaying a lot of pain and anguish. Do seek medical help, and always ask the doctor to explain everything to you in language you can understand, and to write it down for you so you can get other opinions. Your rights are legally enshrined and Doctors now that and have to follow rules.
Take care
Cindy
