I read your blog post and oh, I am so sorry to read of the enormous damage that was inflicted on your property by this storm. I'm in NJ and there are many still without power in the NW part of the state due to downed trees. We lost trees and power for 5 days during the last hurricane so I empathize with your situation.
I too can't seem to knit when I'm extremely stressed. While it is normally a relaxing activity, there is a level of focus that I just can't conjure up when there's something extremely upsetting going on. The good news is that as soon as you start to feel better your knitting mojo will return.
