She\'s gone & not coming back!

Well, my daughter has decided to live with her Dad. I'm still so confused over the whole situation. We had a fairly good relationship. We didn't fight or argue. I just don't get why she had to leave. She told my mom that "mom just doesn't get it". I wish I knew what she meant. I keep praying that she will open up and talk to me but she hasn't said a word. The couple of things she did bring up were insignificant and had nothing to do with us here. She told me before that she couldn't stand her stepmother and now she would rather live with her than me. My heart is broken. With all the other crap I have been dealing with I really didn't need this on top of it! My Holidays weren't going to be very good before and now I don't even care if they come at all. I keep praying for understanding and some peace of mind but so far I am at a huge loss. I can't eat, I barely sleep, my pain level has spiked, I had a massive migraine yesterday, my son's been acting out and has regressed in his potty training. I have tried not to let him see how all this is effecting me but it is hard to be ok when your heart has been ripped from your chest. My panic attack's are back. I hadn't had one in quite a while. This situation sucks and I don't see it getting any better any time soon. Later!
