Ever just want to run away?

Any of you mommies ever just want to run away and go sleep for three days straight? Lol. I’m a FTM to a perfect little 9.5 week old. The only problem is... he cries all. Day. Long. I think I have lost my sanity and I feel completely depleted of all energy. Please reassure me that it does get better... I feel horrible for feeling this way. I love my little guy so deeply... it hurts that his crying gets in the way of what I feel like should be only happy times. 💔 I am never mad or angry... just so sad. And sad for him... surely it can’t be pleasant to scream and cry any time he’s not sleeping or eating.
