You are somebody, and you matter. That's hard if you have a trip coming up that you don't want to miss. The thing is that traveling is stressful, and stress can make psychosis worse. If you go on your trip without dealing with this you run the risk of totally losing control, and being far away from home, maybe in a foreign hospital. I work in mental health (I am also bipolar), and I have had a patient lose it on a plane and get taken off by police and into hospital. I don't want something like that to happen to you. Your health is more important than your trip. If hospital is not an option, at least see if you can talk to your pdoc and get some meds before you go. I still think that you should go to ER if the thoughts of hurting others are strong and you feel like you can't control it. Safety first.
