### input:
My 16 year old son does not speak at school; at weekends and holidays he rarely showers or goes out.He displays OCD going from the bathroom into the kitchen to wash hands / touch the kitchen towel.He refuses to clean up after himself, eg wash dishes he used, his bathroom, his bedroom.I am a single parent, he has no siblings.He did reasonably well GCSEs, but not achieving his potential.Hes bright - doing AS Biology, Geography, Chemistry and English Lit.  Parents Evening was not so good, his mock results (B, C, D, U) more importantly what his teachers said gave me cause for concern as the lack of interaction with others is affecting his schoolwork seminars + group-work, practical studies.

Hello, Thanks for choosing Chat Doctor for posting your query. I have gone through your question in detail and I can understand what you are going through. From what you have stated it appears that you could be having an OCD. OCD is a very common illness and effects many. It can be mild and sometimes unrecognizable, and sometimes it can be severe. You certainly need to be treated for OCD. Although there are plenty of options available like clonal, fluoxetine, Escitalopram, fluoxetine, sertraline etc. my best option for my patients is fluoxetine in higher dosages. Also, there is an option of cognitive behavioral therapy. This therapy is taken by either a psychologist or a psychiatrist in which the therapist identifies impaired cognitions (Thoughts) and try to correct them. They are 15-20 min weekly session and there should be around 8-10 sessions to help you with your illness. Hope I am able to answer your concerns. If you have any further query, I would be glad to help you. In future if you wish to contact me directly, you can use the below-mentioned link:bit.ly/ Chat Doctor.
