Thank you all for your replies
I saw a psychiatric doctor and a mental health nurse.
Used to be on antidepressants for years, and with mood swings those were the worst years so far. Now I'm not on anything, I've found anxiety to be the biggest problem. I've always been, since I was a kid, very obsessive compulsive. Definitely to the point it interferes with daily life, it's mostly about germs, illness, dying. Some crazy crazy thoughts.
However, the mood disorder part is still an issue, but I think if I could get the other stuff under control, it would make a huge difference. Initially didn't want to take anything, of course now I ask to do so, I don't have that option being almost 34 weeks pregnant. So been told to wait it out, use Diazepam for panic, till LO is born then I have many more options.
I don't think I've ever been officially diagnosed with OCD, although I recall my GP mentioning it some years ago. The guy I saw the other day said he could see from my notes that I have a long history of OCD, which I found surprising because no one has ever really discussed it with me. But then, no one has really discussed Bipolar either since they said this is what the problem is. Everyone seems to tiptoe around it all, it leads you to wonder if they are right, if they have doubts etc..
They also diagnosed BPD, which they put on my notes but didn't discuss with me at all, didn't even mention it!
It's hard to know which is more the problem, which should be focused on more or should they both be. This all confuddles my poor brain too much!
But thank you for your replies, they're very helpful
