I'm sorry pboathouse, I answered early this a.m., but I guess i hit the wrong key, it didn't show up!
You're mom had the worst of the worst, mixed states. Depressed, manic and psychotic all at once. This is the one that claims the most lives of all bipolar states.
What happened to your mom is that she was on her way "up" yesterday. When a mood swing up happens, it goes through a short period of the euphoric, energetic "high" before it escalates into classic mania, then psychosis. It can happen really fast, as you witnessed. I'm glad she's in the hospital, from being totally non functional to psychotic in a period of days is BAD. So next, time, if you see a difference of any kind that quick, call her doc and nip it in the bud before it becomes serious. It wasn't your fault, you never know if it's going to get that bad, it's the luck of the draw. Keeping in close contact with the pdoc is the only way to stay well, and we all know it changes drastically from time to time, med changes are a fact of life with this disorder. I have to adjust them about every few weeks to every month, minor "tweaks" to stop the rollercoaster from flying off the tracks, or crashing to the ground. Nice analogy, huh.
How is she doing now? How are you? Let us know, ok?
