Damn I'm sorry to hear that Dylann. Best bet is to go to an outdoors store and speak with the staff, they can recommend the best pack for you and your budget.
There are lots of good brands out there, and lots of cheaper ones. Take a good look at it, are there threads hanging out here, there and everywhere, or does it look and feel well constructed? Go with your gut and the advice of the staff.
How did it happen? (Could be a lesson in it for the rest of us). Remember it's just 'stuff' (hopefully) and it won't effect you in 10 years time.
All the best, hope it works out for you.
