Oh my!!! I know what a mess that can be. I hope your sewing machine and books will be covered under your neighbors insurance. I am so sorry that had to happen to you. Hopefully you will get stuff replaced and get your sewing business up and running really soon.
We had a water leak in our home about 18 mos ago. It took a long time (about 6 mos) to get it all back together and fixed. Insurance covered most of the damage but of course we had to do some improvements along the way. This was a very bad time, I was having surgery which resulted in an infection as well as my dd got married, house was a wreck for the wedding.
