total life decision change!

So I could use some pointers! I was in college for nursing and I'm a CNA now doing home health and I work for a hardware store. I changed my major to business but haven't done much with that as I had an immediate family death recently. I've decided to join the US Navy instead. I don't think I'll do college this fall semester because of that. I'm right on the cusp of weight requirements but need to get in better shape so I don't pass out for being fat lol. And of course studying for the ASVAB. Also, I have really been thinking about it and I don't want kids, ever. My boyfriend is 50-50 but I can tell he does more than he puts on. He's 7 years older than me and says he's fine with waiting for me when I ship out (hopefully within the next year I'll enlist). Does anyone have any advice for anything I've said?! Haha thanks!
