Hello! I have a 6-month-old baby and I'm experiencing severe depression ? I don't want to do anything at all - eat, drink, go for walks, cook, or clean. I just don't have the energy, I just want to lie down and stare at the ceiling ? I often cry, I don't understand jokes anymore, I've become so sensitive and irritable that it doesn't even seem like me. ??‍♀️ My husband is working all day long (and it's getting worse every day). Share your advice, please. Who has been through this and how did you cope?
