((((KJ)))) I am going to talk to you from the perspective of a child that was sent into group homes and foster homes as a kid because my parents couldn't raise me. I was a mentally unstable child. Lots of issues that any "normal" parent wouldn't be able to handle.
Anyways, I am really glad that my parents sent me into those types of places because I got the help I needed and when I turned 18 I went into the wide world on my own. I never doubted my parents love as I was visited often.
Please don't worry so much. I think you did just the right thing. Not only for you, but for your children, too. How could you possibly care for them properly unless you care for yourself first?
I admire what you did and think you are incredible.
