One day, I finally had a breakdown. That was it for me and trying to fit into this world. I couldn't work, isolated, and succombed to addicitions. That was over over 9 years ago!! I have been in and out of psyche wards & inpatient facilities since then. My docs and therapists would only pick up on the bits and pieces of who I was, and I have been diagnosed with PTSD, Bipolar II, Anxiety disorders, Sleeping disorders and who knows what else anymore. I was so relieved when I was in a psyche ward almost two years ago and this doctor caught on the the bits and pieces and ask further questions which related to BPD. I was so relieved to have this diagnosis!! It made sense, and I could now start researching it and deal with it.
I think we have to be careful when we are talking to our docs and therapists too. We are (as BPDers) really good at diverting/avoiding the real things going on in our minds. Think about what things you are really revealing to your providers.

Oh, and the teeth grinding...tell your doc about that immediately. I have tardive dyskenisia from taking Abilfy. It is permanent unfortuanately. I have involuntary jaw movement/teeth grinding now. My teeth are wasting away from it too. So, I would really suggest calling them and talking about it asap.
