Paralyzed by fear....

I lost complete ability to initiate a swallow. Then when I finally did...it was a delayed half way swallow. My left arm and face were weak and numb, and crazy how my legs were going numb also, but they did. That lasted several hours. The next day i was ok. Or maybe i wasnt. Long story short...after being gaslit by a neurosurgeon who refused to order an MRI because he said it wouldn't show past strokes, he then looked at me and said "you've not had a stroke because you look fine"

Finally got in with a neurologist. She ordered MRI of my brain. Two days later my phone starts ringing. It was the neurologist. She said "you have had a small brainstem stroke"

Now...i keep feeling numbness in different areas of my body and face. Also weakness. I can't help but worry. Im so scared of a much larger stroke. Someone please give me advice on how i can best deal with this fear.
