I think you are focusing too much on your W and MIL, and not on you and your boys. Let your L take care of the legal stuff, and if she's not then get another L! Let God take care of your other worries.
Thanks, Karen, you're absolutely right. I know better than to let W get me down like this. And I know to give this all over the the Lord and to turn my focus onto my S's. But every now and then I still get distracted by the senseless drama... Even though I think I am getting better it manages to sneak up on me.
Remembering to just be thankful is always going to be a struggle for me, being the natural pessimist that I am, and so I truly appreciate the reminder.
