PPD and Leave

Has anyone ever used short term disability for postpartum depression? My son is almost 7 months and I’ve been back at work since he was 14 weeks. I’ve been struggling, bad. I’m on medication but that doesn’t seem to be cutting it. My job stresses me out and I bring a lot of that stress and frustration home. My marriage is falling apart. My son doesn’t sleep through the night. I don’t have enough hours in the day between commuting and working and I feel like I’m drowning. I need to see a counselor but my work schedule just won’t allow it. I need time to focus on me and my family. I need time to see through the fog again.
