I think my therapist's main arguments were that
1. there is no med for BPD so it wouldn't help me (though I also have other issues and as some people have said, there are symptoms that might be eased with medication for a while...well, if I'd choose to take it
and
2. if I'll see a psychiatrist, he will only have like 15 minutes for me, so it might be difficult to correctly assess my situation...here I see the point.

My T didn't say "don't go", but he still seemed very determined about this. Now, I would maybe not want to go if I saw improvements, but I don't. Even so, seeing the psychiatrist might not be the solution.
Yeah, I know I'm overanalysing this. I'm just afraid that I'd go there and then will get influenced by whatever he/she says and do that, bc I'm very influencable...especially lately.
