Thanks everyone.
Going back to my first pdoc. A male - not sure how that'll go down with me, but anyway.
He's very professional and I believe he knows what he's doing.
Just going to be a bit awkward walking in and going: Hi, 2 years ago I came to see you, severly depressed. You diagnosed me Major Depressive Episode, sent me to hospital for 3 days and then discharged me. 6 weeks later I was back, following an OD attempt. Thereafter I didn't see you again. I went to see another pdoc (I don't think I'm going to mention that part) and have since been diagnosed and treated for Bipolar. I see a T weekly, and she thinks I may also be suffering from BPD. So, how can you help me?

Lol

Not sure he's going to go along with the bipolar diagnosis in the first place. I do hope I will be able to contact him as needed to discuss side effects. I wasn't really aware of this need when I first saw him. I do know he has an e-mail that he checks regularly.
Oh well, can't be much worse than what I'm in now!
