The thing is, you are not going to ask the right questions if you have had a drink, or indeed get the right advice.
So I agree that waiting until you feel in a better and more in control state of mind might be better.
But that said, I had SS involved after my ex was removed after serious violence (that I had been asking for help with and didnt get), and they basically implied that the violence was my fault and that their involvement was my fault. That if I put a foot wrong the kids would be considered as being in danger (he was gone, police made sure he could never come back). And then was told that their involvement was voluntary but if I didnt agree then they would re-evaluate my attitude, so not voluntary at all!
And then, despite all the "we are not judging you" judging......the SW involved left that job and in the years since I have heard nothing. Case not closed presumably, but equally, no contact. So not in that much danger then?
