I was only suggesting the seroquel in the short term to avoid a full-blown mania until she gets you on something else. I definitely understand why you'd want something else long-term.
I would make another phone call and tell them you are nearing a crisis and must be seen asap. [She] "can't think of another med" is a pretty bizarre statement coming from a doctor who specializes in psychiatry and presumably psych meds!
You just have a little longer to wait, Monday morning you can call and get the process going. It sounds like you are using good coping skills. It'll be over soon, hang in there.
