Thanks for choosing health care magic for posting your query.
I have gone through your question in detail and I can understand what you are going through.
The symptoms that you are describing are very non-specific. You sate that your sugars are very much under control. Try doing Vit B12 levels as that can explain your symptoms.
Also consider the possibility of depression
as even depression can present with such symptoms. Depression is very common among diabetics.
Hope I am able to answer your concerns.
If you have any further query, I would be glad to help you.
