What doctor in TN will help a teen w/ severe, unresponsive depression (who also has no money & Tenncare Ins.)? I've tried almost the entire list of SSRI's, with nothing to show for it. They either cause headaches, nausia, vomiting, or had no effect whatsoever. I've been in talk therapy/congnative behavior therapy since I was 5. I've attempted suicide about 4 times, and went through a long period of 1) using perscription sleeping pills, pain pills, & muscle relaxers to get high, and 2) drinking, smoking, & cutting to fend off the pain. After a brief hospitalization, I ended all self-destructive behaviors in hopes that it would help me recover. It didn't, and while I've still managed to avoid all such behaviors for 7 months now, I long for them greatly every day. I suppose the only reason I don't engage is because I'm sick of the reprocussions that occur when my parents find out. 
My q is this: Is there anyone willing to treat severe depression in a 16-year-old female through alternative methods such as anti-psychotic medication, ECT, or VNS? My current docs are too scared they'll be sued.

Summarized question: Where can I find a doctor in Tennessee who specializes in teens with severe, unresponsive depression?
