Laughing problem?

Ok, this might sound weird but I have this horrible laughing problem. I'll laugh at almost anything; and I always think that things that are funny, even if people don't think that they're funny. I also laugh in a loud, high pitched tone, I can't hold in my laughter either because if I try to then I feel a sea sick sorta feeling(sick to my stomach). I don't know what to do because I am often getting in trouble a school for laughing and I can't refrain from holding it in or not laughing. Does anyone have any suggestions? Is there any sort of medication I could take or medicin which deals with preventing laughter? Or are there any techniques that deal with holding in laughter? I hope someone can help.Laughing problem?
