What your describing sounds like an episode coming/overcoming you.. Is your PC willing to increase your Trazadone? Sometimes Pdocs are willing to use a strong AP for a few days to help you come back down.. Worth a try asking. I personally don't think you should wait til Friday, You could a hot mess by then.
Odd, Lexapro can sometimes flings BP'ers into an ugly mania .
Again I would push the issue with Pdoc you need seen earlier or he/she make a med change or adjustment now .. Before your on the moon.
