Is it likely to get postpartum depression/anxiety again?

How likely is it to have post partum anxiety or depression again if you were to have another baby. I am just starting to feel normal again and over it after almost 2 years of having my sweet baby boy. My husband and I have debated on having another, but we do not want to go thru that again or worse then before( we almost did not survive it as a couple before), but we know we are running out of time for having another and having our kids get along.
