I am tired.. 😔

Breastfeeding hurts.. pumping hurts.. bub is starting to eat more and I am starting to stress about not producing enough. I'm not eating well because I'm so exhausted from the sleepless nights.. he has gas pain and starts screaming if I lay him flat, he's calmest when he's in my arms. 12 days old today and I'm wondering when these baby blues will leave me alone and when things will start to feel more normal.. will he ever switch his days and nights? Will my breasts ever not feel sore? It's just a lot.. I just needed to get that out of my system.
