Is this a mini stroke

M28 Hello im diabetic type 1 now its been 10 years Few days ago i had a headache that lasted for hours and wouldn’t go away with painkillers. My blood pressure was 130/90. I tried drink hibiscus tea and other home remedies, and lots of water. Until the night i felt better then i went to play sports with my friends.

On the way back home i started seeing like a blurred circle in my vision, both eyes were the same. I tried not to freak out and waited until i am home, i was wearing contacts took them out and i had feelings like it was low glucose levels so i measured my blood glucose it was 150 so i freaked out more. I lied down my vision started getting more blurry and i felt very anxious like i was dying.

I waited some time then went to try to sleep it wasnt an easy night i was very anxious.

Today morning i kept feeling tired and dizzy as if it was hypoglycemia but my glucose levels were not low. Then as you may expect i spent today googling hoping to know what this is.
