Hi Rachel,
Welcome to Neurotalk!
I am VERY sorry for all you are going through!
It does not seem right that Washington state would take custody of your children simply because you are using opiates for pain control.
I hope you will be able to acquire adequate legal representation in the child custody issue(s).
Rachel, you might get more individualized support if you copy your post above and start a new thread just for your own story. Just a thought.
You have a unique situation.
Glad you are reaching out!
Warmly,
DejaVu
