Career ending shoulder injury - should I switch hands or hang up the racket?

I have a shoulder injury that may just be the end of my tennis life if surgery and rehab doesn't do what's needed.

I'm not having a good time thinking that I'll never play tennis again.

Has anyone gone through something similar? Did you switch hands?

My kids are about to learn the wonderful sport and I might switch hands and learn with them.

I'm not sure what I'm after, just a bit depressed at the moment.
