Hi SCA
I'm glad you found us
I don't think anyone ever went through a situation like you are knowing exactly what to do - but you'll find a lot of shared wisdom and experience here
A lot of people find face to face support in things like Al Anon.
We also have a forum here that Sazzle mentioned above - you might like to check that out as well:
