Would you get back into a job you hadn't had in a decade?

I was a nanny for nearly twenty years when I accepted my last job a decade ago in child care. I write sometimes about having low self worth and low esteem at SW because it is crippling. Grew up in severe abuse so over time I believed I was worth less than dirt. BUT ,one thing I could say positive about me, was that I was great with kids. Patient, loving and I did engage them in any way to learn new things.

Then because I got super anxiety about accompanying the toddler I was watching back then in an ambulance, (I have extreme anxiety as a passenger in vehicles), I never got a reference and the mom belittled me so much. The dad was very kind and thanked me for helping his sick child, Bec I had called 911. The toddler was so hot to the touch and vomiting excessively.

It took me YEARS to not think of myself as some bad nanny over that one day. I have not gone into child care for ten years because of it. But I'm slowly seeing the mom DID overreact and I am a good nanny. He was safe every moment getting to that hospital even if I wasn't in it with him.
But now, I only have one child care reference from years ago as an assistant teacher, and I'm unsure if I could use another nanny reference from a teen I watched, ten years ago too. Would two references that are from many years ago be enough?
