Thank you both for replies. I have been to the GP and I'm having counselling, but it just doesn't seem to be shifting. I'm not on antidepressants because I required huge doses of many antidepressants before, and none of them seemed to help for long. (And I'm still breastfeeding.) I hope to god it doesn't change into regular depression, I'm not sure I'd be able to deal with that.
Teal, do you mind me asking what you're taking and how much?
