Hello,
Welcome to the ehealthforum and I am really glad to help you out. The symptoms that you have mentioned are typical of Asperger syndrome. Intense preoccupation with a narrow subject, one-sided verbosity, restricted prosody, and physical clumsiness are typical characteristics of this disease.
You need cognitive behavior therapy and medications like selective serotonin reuptake inhibitors and atypical neuroleptics. I would suggest that you consult a psychiatrist in this regard. It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For an exact diagnosis, you are advised to consult your doctor. I sincerely hope that helps. Take care.
