I think you may be more at risk of depression, topmammy but not a certainty by any stretch. Mine was brought on by absolute sleep deprivation - she was waking 12-15 times between 8 and 2/3!! - and then just not at all coping. I don't have friends or family around me where I live (they're an hour away) so it was very tough for me. I would advise not to worry about it and if you start to feel overcome by it all, then ask for help and not try to struggle through like I did. Made me sick. I didn't get meds or I'd have needed to have stopped bfing, which I enjoy and at that time gave me the bonding time I needed with dd.
choccy oh how I know that feeling of desperation! See above re waking times - went on for 18 whole weeks!! Felt like I was actually going to die!! It was so hard because all the hv and docs kept saying was "leave her to cry, don't go in to her or she will have won". (Won?! Really?! Omg!) They didn't have any other options for us, even though we kept on saying that's not our style. Just contributed to everything getting too much for me. Anyway, I'm stronger now and have accepted this is our life
