Go for it.
So happy for you.
I has always wanted to have a career, but it became a last priority due to circumstances, moving to another country without work visa, kids as well problems with h. Now with empty nest, I am all set towards that goal. I have never backed out from a challenge in my life. I do question whether I can do it at this age, with my h's condition, my future roles as MIL & grandma. But it is best to face the challenges & reach my goals anyway rather than regretting not doing it.
