I could be wrong (it's happened before, I hear - lol) but I don't think you can "set yourself up for ppd". If you're struggling with depression and it's going on for a while, you really might discuss it with your doctor, though.
Depression isn't a good feeling, and I sure do hope you are feeling better very soon.
Congrats on the addition of a little one to your life :)
