Glad you stepped in from the shadows, Rhonda, and joined us.
I too am the mom of an addict, and it took me a lot longer than you to realize that "we" are not their only option, we're not even a good one, and our homes are not rehabs.
You did the right thing. I remember years ago at a time when my son was in detox and not allowed to leave, I went to a shelter to pick up his things. It was a Salvation Army shelter and it was clean, had good nourishing food and counselors available to help any residents who wanted help to get into a rehab. I was never afraid of shelters again.
Sending big hugs because most times it's just hard to be us and to do the right thing.
