Counseling for S14 ASAP and maybe the other kids too because S14s behavior is gonna scare the sh*t out of them too.
As for hearing them, that is what you are there for.
I had a total tantrum freak out cry-fest this morning (because it was the first 4th of July without my kids and it all hit me).
I ended up speaking to my step-dad. When I told him how horrifying it is for me to see my kids going through what I went through as a kid and to know what they are feeling, instead of telling me to stop projecting or talk me out of my feelings, he told me a) that he understood and it makes perfect sense and b) what a gift it is for them to have someone who understands and can feel for them and empathize as I am able to. Well, the dark cloud lifted and not only did he make me feel empowered and compelled to be here for my children in a way only I can, he also exhibited how it is done.
So, they are blessed to have you. You can handle it (yes, stealing from Coach)...
