Pat,
You have every right to be "out of sorts". Seriously, you've earned it. Your lives have been turned upside down, shaken, and thrown about. You didn't ask for this, and you wouldn't wish it on your worst enemy. I felt better when I finally learned to allow myself to have bad days. I realized that those feelings are part of the deal, and that they won't last forever. It's good that your Mom is there to help. Moms are good. Remember that you've earned the right to not have to be a superhero every single day. For me, things became a lot easier when I gave myself permission to just give in to it now and then. And, Rex and your Mom probably understand more than you know. Hang in there, Pat.
