feeling isolated and jealous

My sweet baby girl is 11 days old ! She is wonderful, cries some but is easy to console. I love her so very much but I'm starting to get emotional and jealous that my husband gets to go back to work! I love my daughter and enjoy spending time with her and worry when she isn't in site but sometimes I wish I could just leave for an hour to get groceries. I'm a FTM and breast feeding so can't be gone to far or long. I know time will go by quickly but I am patiently waiting to not feel so jealous. Baby and I go for walks, cook and clean together, eat and sleep (well she sleeps). I know it's normal, but I think I need some more support. I try not to let it get me down but sometimes I just cry :(
