Hi,
Thank you for posting your query.
I have noted your details and it is likely that your symptoms are related to too much thinking or 
anxiety.
You should relax and remove all anxiety-related issues.
If your symptoms still persist, then, you should 
consult a neurologist for evaluation. 
Investigations such as brain scan, 
vitamin B12 level and 
thyroid tests may be needed.
I hope my reply has helped you.
I would be pleased to answer, if you have any follow up queries or if you require any further information.     
Best wishes,
Dr Sudhir Kumar MD (Internal Medicine), DM (Neurology)
