Wow, what an inspiring story! At 30, I thought I was too old to attempt changing careers, my family is supportive except my girlfriend who ridicules me of not knowing what I want to do in life. Sometimes it causes doubt but after volunteering at hospitals (yeah I know it's not close to what nurses do), I'm certain that's what I want to do, care for people which I'm good at and at the end of the day feel like you actually accomplished something, no matter how screwed up the day went.
Thank you so much for your story and please do keep us updated!
