Well, what do you want to do? The only way to get answers is to seek professional help. There are other therapists and doctors besides the ones you've seen. I've been through I don't know how many doctors, therapists, and meds until I found what worked. I was diagnosed with depression 20 years ago, with BPD 10 years ago, and have been in the hospital 4 times. I was also (incorrectly) diagnosed with bipolar when I was 16. I took the meds they gave me, and they did help a little; they are very similar to the meds I am currently prescribed. I assume that you live in the United States? You are usually able to choose whom you would like to see. I got second, third, and fourth opinions. I went to different therapists until I found a fit. I don't really know what to do when you're under 18, or what do do about the diagostic criteria, but that is a question for a professional.
