Thinking about going back into the navy but i’m unsure

so about this time last year, i started my training, did 5 weeks and decided to pvr as i had a lot going on personally and i couldn’t deal with it properly, when i was there i also felt like it wasn’t right, though i really enjoyed some parts of it, and the lads i was with, but the military is something i’ve wanted to do my entire life, and since i left i have struggled massively to find anything remotely interesting to do for a job, i’m thinking about going back but i’m second guessing myself based upon last times experience, any advice would be appreciated.
