Depression

So tomorrow I go to the doctor however I'm seeing my nurse practitioner cause my doctor will be out of office. My depression is getting worse. I was on medication when I had my first daughter because I had PPD I'm just wondering if there's anything they can do for me while pregnant or if I'm just wasting my breath by telling them. I really want to breastfeed so I've been trying to just "ignore" it but it's just getting worse the longer  I go. I do plan on calling my insurance to see my cost options on therapy also.
