I think you should ask your T what she means. I have CPTSD and bipolar 2. I've been dealing with this crap for at least a couple of decades and have been treated for it since 2003.

My ptsd and bipolar tend to feed off of one another. My ptsd is from childhood abuse. I don't know how I got to be bipolar except it was more of a gradual illness than ptsd.
My ptsd gets triggered which can throw me into a mde from the bipolar and around and around I go.
Take your time, try different treatments and meds as recommended, and eventually you'll find the right combination that works for you.
If you have any questions or concerns, please feel free to message me.
