Could you try sitting up a bit in bed? I suck gaviscon tablets when it gets too uncomfortable; avoid fat; and eat slowly - I find that helps. Sometimes grazing can help rather than having big meals. And feeling upset can make it worse - and goodness knows you have plenty to be upset about.
I hope that this problem will settle and you will be able to get some sleep. What difficult times for you.
