Are you serious? Im not going to lie I D.A.O.R when I was at the AFC 6 years ago when I was 16 after doing 26 or 28 weeks cant quite remeber, but my point is I gave it quite a go and realised I wasnt ready (maturatity wise and fitness wise), I now am waiting on my date for catterick and have made sure that Im not going to waste the training staffs time by increasing the difficulty of my training since selection by several miles (completed my first 8.5 mile run on monday), started wearing boots just to get used to them and am brushing up on a bit of map reading skills.
Basically im preparing myself in hindsight on the subjects I wasnt good at previously before, did you do the same before rejoining? Just get a grip of yourself and take it on the chin, your going to feel homesick thats understandable but jacking in after 8 weeks? Just remind yourself why you joined back up in the first place. Also just food for thought if you are at catterick just think, that could have been someone elses place your taking up matey. Good luck in whatever you do, but dig deep and bags of determination will see you through it.
