Postpartum depression mommy's

J
I'm 9 weeks pp and I have always been depressed but never taken any medication for it. Since having my son there will be days I just want to lock myself in a room and just sleep or I just want to cry all day and not be around anyone. I'm thinking about calling my doctor and telling her I'm depressed but I'm just worried if I will, will I have to stop breastfeeding for one. Second I'm nervous about being on medicine and how I will act on it. Please any comments or give advice would be much appreciated.
