Look for humanistic, maybe. I've had great success with bpd issues with psychodynamic / humanistic stuff. I'm on my way to being cured of it.
T tells me I'm almost there. But he's brilliant.

If it makes you feel more comfortable to disclose it before meeting, then go for it. But not all people with bpd are the same. I actually think many people with this disorder are some f the most interesting I know! Not all T's stigmatize.
