A few disorganized thoughts after reading your post...

1. I don't think ship captain is the right path for you
2. I think you'd make a great therapist
3. I think you should consider pursuing writing as well. The bit above is a bit of a brain dump so it's hard to say for sure, but my gut tells me you have a lot to say and if you can find a way to refine it, it would be really interesting to read

You've got your life ahead of you, and you're asking the right questions. If I were a betting man, I'd bet on you doing something amazing with your life.
