Hi there!
We find it helps our child, tho we can't stop the crying and drama per se, but we can help child determine on a scale of 1-5 where 5 is terribly awful because there is blood and 3 where there isn't and 1 where it is just a little bump.
This scale is useful for many situations where it helps child to determine/clarify for themselves how to react to something and evaluate the seriousness of it.
You're not alone. Many of us have a child that just keeps going and going. We *do* use the TV. We pre-record like Martha the Talking Dog or some other well-written show. For when child was younger we did watch Timothy Goes to School. I know not everyone agrees on the usage of TV but sometimes I need a "pause" and I send myself to "time-out"

Of course it is not possible with a 6m old also, but see if you can get some help too, so you can take a break.
You are welcome to rant here and let some of it out here.
Take care!
