Going back to work

I was just wondering how you all handled going back to work after maternity leave? I only have 8 weeks off and they are going by fast and it's making me upset. I already have anxiety about leaving my baby with someone everyday. It doesn't help that I have two really good friend that are having babies very soon and both get to quit work after the baby is born and stay at home and that's all I get to hear about 24/7. I just need advice from people who went through what I am because I obviously can't to my friends. :/
