While I don't feel I am, I can't convince my team that I'm not. I have tried cognitive restructuring of my thoughts but it hasn't helped. I really don't want to be stuck anymore, but I'm scared of the unknown. My Therapist doesn't help me in this area. I am not sure what to tell you.
Any new treatment has the risk of success or failure.
If you are happy with the way things are going, then continue to do more of the same. If not, then you need to change. We have published extensively on using medications in borderlines, and there are a number of letters in the archives of this site covering their use. Personally, I am a proponent of change if what one is doing is not working. If your doctor and therapist feel seeing another party for a consultation is indicated, it is probably in your best interest to do so.
