Hiya! Glad your house warming went fairly ok.
Yes I get into those 'funks' sometimes. My hubby says he can walk out of the room for 2 mins with me smiling and then come back into a face full of sadness for no apparent reason and he is right, there is no reason at times, it just happens. But like they can quickly come they can quickly go. It's when they stay is the problem.
But you are ok now and that's what counts
