Struggling After Childbirth

My pregnancy was tough and the delivery didn’t go as planned. I ended up having an emergency C-section, and me and my baby had to stay in the hospital for three weeks because we both had complications. Now my little one is almost 4 months old, Alhamdulillah. I’m dealing with a lot of anxiety – I barely sleep because I’m always on edge – and sometimes I just feel overwhelmingly sad and cry without knowing why, even though I love my child so much. I started therapy, and my doctor put me on antidepressants and something for anxiety. Both my doctor and the psychologist say it’s postpartum depression. Alhamdulillah, my husband and family are really supportive and help out as much as they can. That’s actually part of why I don’t get why I feel like this. I’m scared to take the meds because I worry it means my iman is weak. As a Muslim, have you ever taken these kinds of medications?
