Some of your symptoms sound like bell's palsy. Nothing related to strokes.
If medics have ruled out strokes then take it as cleared. They do plenty of checks.
Hypos whether true ones or false make you feel all those symptoms. Underactive thyroid too.
Any coldness when people are saying temperature is fine?
I was ill for a while before underactive thyroid diagnosis. This causes depression and low mood too. On top of hypos. It would be very very much like you describe.
Call gp practice tomorrow and ask for last blood test results and whether thyroid was checked and if totally fine. If close result make an apoointment to see your gp for possible low dose levothyroxine.
All the above can be autoimmune related. As your type1 diabetes.
You are right to wonder what's going on. See a different gp at your practice for a fresh look at it?
Let your gp tell you what could be happening. Don't prompt gp.
Pls get thyroid checked thou asap, if wasn't included in bloodtests.
Pls let me know how you get on. Neither wonder your worrying. You just want to know what's going on.
Hypos are very upetting and emotional. See your dn for a refresher and let her know by meter how many hypos and symptoms even when not in 4s.
I'm confident this can be explained and resolved. You shouldnt be having to suffer this in the dark!
