Have you ever felt like you were “born” for a specific reason, or that you had a specific calling in life? If so, what is it?

I never had big dreams, but I always felt like I was supposed to be in the military, and that was the one thing that was my calling. Unfortunately, I have aortic stenosis, and I am unable to join. The day I found out was the most devastating day of my life (ha, so far). I cried for hours and was so lost on what to do. I wandered aimlessly from job to job for years before I finally settled on a job in the healthcare field. I still think about “What if” all the time, though. Anyone got anything similar?
