PTSD is a very tough illness to deal with so I can understand you are trying to avoid it but destabilising yourself will only make things worse and your PTSD will make things worse. As difficult and overwhelming as it may seem dealing with your PTSD will make your overall health much better. Do you have a T you can process this stuff with? If you go ahead take it really slowly and have breaks when you need them. If you go off your meds there is no guarantee that your PTSD will go away, in fact it may get worse and you will also have the Bipolar to deal with. It is a BIG risk.
