I've been diagnosed with both (bipolar and bpd) plus PTSD by more than one professional ... I don't understand it all the time. .. other times... well, I try to understand and get it to a point.

And it's funny to me, in a way, that if I'm with one psychotherapist professional that specializes in on one (or the other)- they have claimed at times that they don't "see" the other or are unsure, or at times agree what a pdoc wrote... but pdocs... they keep the same three labels,..... humans make errors though, as do I...
The bipolar therapist was big on dbt as was the bpd therapist... all pdocs want me to take their cocktails... stop my self medicating, that's gotten me by so far....
Sorry, I'm rambling ... any ways

I keep this bookmarked
