Order news strings now.
If it's really through one, based on your timeline and no backup bow, you will be fine. I would shoot it. I wouldn't shoot it a lot though and get it restrung as soon as you get back.
If you have a press, press it out to confirm the strand count. More than 2 or 3, I'd look for a backup bow or expedite some pre-made strings and get it swapped. 60x has a bunch of premades.
Learn your lesson for next time though. If you don't have a backup bow (which I recommend) get 2 sets of strings. Shoot 100 through 1 set, tune it up perfect, take it off. Put the other set one, do it all over again and use that set. Now you got a prestretched backup set, 99% tuned as long as you don't lose or gain twists in storage. Then when your current set is ready to swap, get a new set, tune that up after 100 shots, take them off. Then pull out last year's set and use that... You see the pattern.
I was retying a peep and cut off the serving and accidentally cut through a couple strands. Luckily this was July, but you are always bound to have accidents with strings and bows at some point!
