Hey cam, I know how the LBS feels like they're all to blame.

Number one thing you'll have to figure your way out through, and move on from, is...

You are ONLY responsible for YOUR share of the problem.

You could become confused as to what specifically is your responsibility. The WAS may blame the LBS for a LOT MORE than the LBS's share...

Search deeply and figure out what is yours to own, then own it, forgive yourself and move on.

While you're doing that, GALing will help take your mind off things so you can detach and think clearly about how to proceed.
