Dear CaliGirl, have you ever heard of the saying "one day at a time"? It is an old AA saying, and it is what gets a person from one day to the next when it all seems too overwhelming and too confusing to bear.
You don't have to solve this in one day, and you certainly can't predict the exact future when it all hinges on someone else.
I think that the very most important decision you can make today is to get help and support for yourself. Go to an alanon meeting would be an excellent first step. Read all the "stickies" at the top of this main page. Come here and read---and keep posting. You will find that others have been in your shoes and understand everything you are going through. You don't have to go through this alone. I think that your being in therapy was an excellent decison on your part!
Keep your faith,
