Scared of PPD

Is anyone else terrified about having PPD? I suffer from depression, and havent had to take meds since being pregnant . I'm terrified that I will slip into PPD after I have the baby . My Husband works offshore and I will be mostly alone with the baby while he works. I'm scared the stress of a newborn with little help will.bring it on . I'm.def going to talk to my dr about it .
