I'm a teenage female diagnosed with bipolar disorder, depression with psychotic symptoms, and PTSD. Today at school I was walking to another class, then I have a gap in my memory except for some vague images of a bathroom, and then I found myself walking around outside the school. I had my coat & bags like I was ready to leave, but it wasn't the end of the day. I got upset since I had no idea how I had gotten there or what was going on. I've had a headache all day that sort of travels around my head, and after the episode I've also had back pain.
I have ongoing back problems, so the back pain was not unheard of for me before. I'm currently taking lithium, risperdal, zoloft, vistiril, buspar, & triprevifem. To my knowledge nothing traumatic or upsetting happened while I was walking to my class. So does this sound related to my bipolar diagnosis, or another problem?
