All I can say mate is that whoever you end up joining you're not going to be alone in putting up with hard times. In the Corps it's true to say that if you can't take a bit of stick then you're not going to become a bootneck - a lot of it is about just putting up with things and remaining cheerful. It's hard at times but it will stand you in good stead throughout your military career and throughout life. Morale is everything in the forces.
Any grief from training teams won't (particularly) be personal unless you show yourself to be worthy of attention so keep your head down and crack on as best you can. Always look to help your oppos - one thing guaranteed to attract 'attention' is somebody who is 'jack' and looking out for themselves all the time - bootnecks aren't made that way. Never make any excuses and just take things on the chin - a common gesture in the Corps when I was in was to flick the chin as if to say 'am I bovvered?'. Don't take things personally (that's easier said than done some times) and try to keep smiling.
