Finding it difficult

Hey everyone,

My LO is 3 weeks old and I'm really struggling today. I'm finding breastfeeding really difficult. She was born at 37 weeks and was small so has had trouble breastfeeding. She's doing better now but every feed is supplemental by a bottle of expressed milk. The whole process is just exhausting and is made more difficult by the fact that she isn't wanting to be put in her crib a lot of the time now. I know all this is part of having a newborn but I just feel so empty and it's making me feel very down. I feel like all I'm doing is feeding, expressing and getting her down and then it's time repeat the process. Does this get any easier?
