No appitite. Breast feeding

My baby is 15 days old now and is doing fab! The problem is with me. Not sure if it's linked but I'm very emotional and have no appitite at all .. Nothing sounds good to eat not even my fave foods. Managed a banana smoothie that was in the fridge and three chocolate cookies so far today but it's 2pm... Any tips to increase appitite or did anyone else feel like this so soon after giving birth. It's so weird usually love my food and been starving my whole pregnancy! Xx
