Hello
I have gone through your query and understood your concern.
11 yeard with diabetes can produce complications like
peripheral neuropathy and can exlpain the numbness in your extremities. The difficulties to hold onto things with hand can be due to a possible
Carpal tunnel syndrome.(The tests will clarifie the situation)
But the problem of falling and the balance issues can not be attributed to your diabetes.
From the description of your problems ,in my opinion all your symptoms can have a neurologic basis.(
Transient ischemic attack (mini-stroke),Multiple
sclerosis etc.)
For this reason i suggest to
consult a neurologist because you need to do some specific neurologic tests to reach the right diagnose and than you can have the right treatement.
Don't worry i don't think your actual problems are life-threatening and with the right treatement,you will feel much better.
Hope my information is helpful.If you have other queries,feel free and ask.
