Welcome Rush. I am sorry you are going through this ordeal with your daughter. Your story is not unlike my story or many others on this site. We are all on a strange landscape which has mine fields everywhere..........
It's a good idea to get your daughter on medications, however, her staying on them is up to her. I don't know if you've already exhausted resources, but a good place for us parents to do some research is NAMI, the National Alliance on Mental Illness. They have excellent courses for parents to help us cope and to learn tools to make OUR lives better. If you haven't already, I would find a therapist for YOU. So you can get comfort, understanding and the strength and resolve to begin to learn about detachment. You may want to read the article at the bottom of my post here on detachment, it is very helpful. Sometimes the best thing we can do for our kids is to get help for US.
Our kids can do remarkable damage to our relationships and our own well being and health, so it really becomes imperative for you to take care of you. Once you start that, the solutions to how to deal with your daughter will present themselves.
For me, the process was about setting very strong boundaries. Which to begin with means, what can you live with, what can you NOT live with, what do you want, what do you NOT want............get very clear on all of that so you can then present a united front with your husband as to what the rules of the house are. In addition and equally as important are the direct and unbreakable consequences if your rules are not followed. That is very important, regardless of her diagnoses. You might want to look into the rules of eviction in your state and if you need to get a court order. Once you know that information, present it to her. She doesn't follow the rules, the next step is eviction. Or as some parents have done, you can place her in one of those low cost hotels that are cheaper because they essentially deal with transients. But that is entirely your choice. Sometimes YMCA's have options as well. If there are no shelters, then she has limited options.
The bottom line is that you DO NOT have to deal with your daughter's choices for the rest of your life. That is always your choice. Once you've established strict boundaries and consequences, if she does not abide by them, then you need to follow through on whatever your choices for consequences are. If that is eviction, then you have to learn detachment because it is not easy to evict your own child. Mostly we parents get to the point of exasperation and depletion before we make that choice, but most of us do get there. Our kids are masters at manipulation, drama, lying, stealing and often laziness..............so really, it is up to you to change because it is very likely she won't. That's where professional support comes in, most of us need help to make these difficult choices.
Hang in there, you're not alone, we understand how you feel. Keep posting, it helps. And, get yourself some real support for YOU.
