Does this sound crazy?

I’m 30, I have two kids. One is 4 and one is 1. I have a good paying job but it doesn’t fulfill me. I really want to go to nursing school and eventually become and l&d nurse. I went to college more than 10 years ago and don’t have a degree in anything. We could live on my husbands income but it would be tight.

I don’t know what to do or what’s actually obtainable!

Any advice welcome.
