Thank you both for your replies. I did read them last weekend before my appointment and kept them in mind--just didn't feel up to stringing together words for a reply yet (nothing would quite connect, you know?).
Merseamud-- Thank you for relaying your experience. I'm not giving up on therapy, because despite the issues I've had with it, I've gotten to know a lot about myself as well. And I also know that even though I'm always a mess, I've been significantly more so since terminating sessions (I also had a tendency to call my therapist between sessions in crisis mode...). But anyway, that's another story--kinda the point is that I've gotten to know myself somewhat well enough to know that, while I don't expect therapy to "un-break me," I do know that having that support system is an important factor for me--otherwise I explode inside my own head (which I do enough of anyway).
However, I'm not ignoring the medical side. I actually saw the doctor this week as well--a new one, from the same clinic. I decided to be completely open with her. She put me on two new meds--one for mood, one for sleep--in addition to my current anti-depressant (which hasn't done a thing so far). So we'll see how that goes...
iate- I get what you're saying completely. As I mentioned to Merseamud, I'm by no means new to this and didn't really see any patterns until months and months of my therapist pointing these things out to me. And I'm certainly not an "Oh, that's me sometimes." It's repeated, and very, very damaging to a lot of points in my life. As I said, though, I'm still not convinced that that's what's going on...I mean, it's all VERY confusing.
I took your advice and didn't tell the new therapist about the dx. I also didn't tell the new doc, although I was very open about what I experience (for the first time ever with a doc....I actually felt comfortable with this lady).
All I know is I need help. Too many things are going too far out of control...
Thanks again

EDIT: I just noticed my original post says I'm 20...I meant to say 20s. Not that it makes much difference, I guess, but it was bothering me haha
