Reg, very sorry to hear, but it is far from the end of the world and you will get better, it takes time.
My sister had a stroke about 2 years ago, she has made a complete recovery, the only lasting issue is a tendency to get tired more easily than before. But that could also be age.
She had her first vaccination with no side effects, about a month ago.
As others have said, go with the medical advice!
