Welcome aboard. I'm wondering if you would be well served by what was suggested above, one of the immersion courses in England
. It's a relatively short time investment, and you'd certainly have found out if you enjoy sailing, find out about sea sickness
, learn about sailboats and have a structured re-entry phase to civilian life. It would also give you a break and a chance to plan the rest of your life in a much lower stress environment
I understand what the other posters are getting at who are saying in effect that for another 10 yrs. of your life in servitude, and especially if you're able to invest portions of your pay, you could be sitting pretty at age 29.
Actually, I think you're facing a hard decision. I wish you the best of that, sometimes it aint easy, and you just have to jump.
