tbidaughter, welcome. I'm sorry you're going thru this with your daughter.
I don't have any advice for you about how to ensure she receives the right care.....what I can offer you is encouragement to make sure you get support for YOU. It sounds as if you've been living a nightmare for quite awhile. I'm so sorry. I know how devastating it is when our kids go off the rails, for whatever reason. While you maneuver thru this situation with your daughter, make sure you get support.
You matter too.
You might find support thru NAMI, the National Alliance on Mental Illness. You can access them online, they have excellent courses for us parents, you may find information, resources, guidance and support thru them.
I don't know if your daughter has been abusing substances, if she has, you might try 12 step groups, Al Anon, Narc Anon, Families Anonymous and CoDa have offered many here solace and support.
Many of us opt for private therapy and support groups as this stuff with our kids can be devastating, we are exhausted and burned out and often as we put the welfare of our kids above our own, we become depleted, depressed, anxious and suffer with a form of PTSD. I would encourage you to find a strong support system.
Continue to post, it helps to write it down and have your post received by others who understand the gravity of the situation, won't judge you and can offer you compassion and support.
Hang in there. You're not alone......we've all struggled with the choices our adult kids have made.
