Welcome to HCM!
I have gone through your query carefully and from that I feel that when your CT and MRI
Brain both are absolutely normal, this almost rules out anything related to organic brain pathology....you have mentioned that you remain anxious, this makes a possible link with your presentation.
You should meet a psychiatrist
and get a detailed evaluation done. I don't think you are clearly aware of any problem/ stressor, so, need to go for some psychological testing.
from what is mentioned in question, it looks like you have various somatic symptoms and will be helped by giving SNRI
, like., venalafaxine, in a dose of 37.5 - 150 mg, once a day.
But my sincere advice will be that you should go and meet a psychiatrist in person and get treatment.
It dosent look like you have any major illness ,so please donot worry, it can be helped.
Hope you get wells soon
Feel free to ask more questions
