Hi Phattgal (love the name!) - sorry to hear about the PND, but congratulations on the birth of your dd.
I have had it after all three children and am seeing a psychiatrist for counselling as well as taking antidepressants this time, my dd2 is 12 weeks old.
I have taken the same antidepressant each time, its called sertraline (Lustral). It's especially suitable for depression with anxiety and I've found it very good. It's also fine with breastfeeding, if that is an issue for you.
The other symtoms you describe are totally normal for depression (I'm a bit of an expert these days I'm afraid. Also my dh is a GP so I have talked my depression to death with him!). Many people get physical symptoms along with the mental ones - I get indigestion and also dizziness like you. Anxiety etc is normal. The doctor may also ask about your sleep, appetite, sex drive (hahahaha at 3 months after giving birth!).
Your GP may suggest counselling. Most research shows that for ordinary PND counselling is as effective as tablets, and the most effective treatment is both together. Some people also use hormone therapies but to be honest I know very little about them.
You should know that antidepressants can take 2-3 weeks to work adn sometimes you have to increase the dose to feel fully well. You will also have to take them for at least 6 months. Most of the modern antidepressants have few side effects, mainly they can make your bowels play up a bit! They are also mostly not addictive, the only one that has real problems is one called Seroxat which most docs have stopped prescribing as people had trouble coming off it. The others you reduce the dose over a few weeks and I have come off mine on more than one occasion with no bother. They don't make you sleepy or anything.
I hope you get this sorted out, and can start enjoying your beautiful daughter. It is awful, but I can seriously say that it is worthwhile taking medication as it can take months and months for you to come out of it on your own (on average I think that unmedicated mums take 7 months to recover, but of course many take a lot longer) but on the tablets you will be functional and enjoying life again inside a month.
big (((hugs))). Let us know how your appointment goes, and how you are getting on. Our dd's must be about the same size and at the same stage! Be nice to yourself, and make sure you get as much rest and pampering as you can.
love
