Why does this anxiety creep up on me?

It shouldn’t be the case now that I am free.

Free to go and do what I will but the pounding of my heart stops me still.

I blame my mobility which isn’t great, my age is advancing at a terrific rate.

I know many folk who are very much older, I admire their strength and resolve why can’t I be bolder?

I feel lost and at sea a prisoner of my anxiety.
