Bummed!!!!

OK,I need to vent!!! A couple of weeks ago I did a really big order for this lady through my Etsy store!!! I was super excited about it!!! I had made some scrapbooking pages (8 of them!) you can click here to see them! Then I made her a card and additional baby critters to go with them!!! You can click here to see the baby critters and here to see the cards. Anyways,I've been selling on eBay and Etsy for awhile now ,with no problems!! She says she didn't get her package....But,I mailed her package to her on May 27 and I paid for the confirmation shipping which said it was delivered at her correct mailing address on May 29!!! (I could kick myself for not getting it insured or something!!! But,I never had a problem before,so it never crossed my mind to do that!!! UGH!!!)
  It states on my Etsy that I do not give refunds.....but,I want to make it right with her...so now I have to redo that entire order!!!! The cards and baby critters will not take but a few days....but the 8- two page scrapbook layouts will take weeks to complete!!!
 Has anyone else ever had something like this happen??? I'm seriously thinking about shutting down my Etsy now!!!Thanks for letting me vent,on top of stressing about my oldest leaving on Sunday,now this!!! I hope your day is going much better than mine!!! :(
