Oh Fay you poor thing, I'm so sorry to hear that.
I'm with Dolly, unplug your phone. You shouldn't be stuck in the middle.
If you need a Scotch and Coke, perhaps use Diet Coke, it at least cuts the calories and if it doesn't taste as good you won't go back for seconds......
Hope things settle down for you soon and you and your son get what you deserve - to be a big part of those kids lives.
My thoughts are with you,
