Loosing weight

So. My baby is 5 months already and I'm still trying to lose my baby's weight and it's so hard. I work overnight and I try to get some sleep during the night but sometimes I don't get that much sleep so I'm always tired. And I try to lose weight but it feels like I'm hungry and I want to eat and eat. And I don't have any clothes and my shoes won't fit and I'm just feel like I'm getting my emotions down and I feel ugly and fat. Does someone has any tip for me?

Here is me and my little one. ❤️❤️.
