So sorry to hear this, Christina. It's awful when everything goes wrong at once. You're a lovely person. Please be gentle on yourself, no matter what happens. You didn't ask for this, and are doing your best to manage it.

Take it all one difficulty at a time, if you can.

Just deal with the thing right in front of you.

It's hard to think when we feel like this, so don't try. I find it helps to write on a calendar, in large letters and in a place where I'll see it clearly, the appointments I've made / calls I'm going to make / essential bills that need paying etc. Then I can relax a little. Not feel so bewildered by it all. Let some time pass.
