doctor just asked me what I wanted her to do about it?
Aaargh. I think they've started asking this in an attempt to understand patients' wishes/make them feel empowered or something, but I hate it. Unless they're very careful with their tone it can sound flippant/dismissive/borderline aggressive. And the truthful answer would often be "I don't bloody know, do I? If I knew how to fix this, I wouldn't sodding be here. I thought you were meant to be the expert...."
The fact that the GP didn't risk assess you shows they were not exactly at the top of their game in that appointment.
I think going back and maybe seeing someone else is a very good idea. The basic treatment options are
- meds
- talking therapies
The doc can prescribe 1) and refer you to 2). Recovery rates are highest when people do both at the same time, but it is a very personal decision that can depend on lots of different factors.
The thing about 2) is that quite often you'll get referred to IAPT as a first-line treatment. IAPT can be great if you have relatively mild depression and/or anxiety, but it isn't always the right service for everyone. It's different in different areas but my local IAPT has no perinatal specialists, for example.
Ask the doctor what services are available that specialise in perinatal mental health, and ask to be referred to them if at all possible
It can be very difficult to talk about but do tell the doc about the dark thoughts if the second one doesn't ask. It can have quite a dramatic effect on their attitude.
