HEEELPPP First day back at work after baby

Whhaaa monday was my first day back after being on maternity leave 3 months. im having major seperation anxiety. my baby girl is doing great eating like normal..little piggy but i miss her so bad. im pumping at work and im making about 12-14oz after 3 pumping sessions at work...nd then i pump again at home. so ill make juuust enough for her to eat..and ill also give 1 4oz of formula to help fill her up or shell eat my entire supply. lol shes with her sitter monday through friday. thats taking some getting used to...being away from her..butttt im feeling so overwhelmed at the office...managing my baby and my husbands 6 year old daughter..feedings..work...money issues. im sooo stressed out all i want to do is break down and cry. does this ever get somewhat on a schedule or normal??
