Newborn blues!

Having a newborn is so much work! I had an emergency C-section and my baby is now 2 weeks old and everyday I feel the challenge. I’m tired of everything and sometimes I just want a break from being a mum, I don’t know if that’s normal to think so early on but I just feel like I need some time. I love my baby girl so much but the constant routine is so exhausting. I guess I just need some clarity on whether this is normal to feel or am I just overthinking things?
