Ready to lay down an epic rant

As a FTM I have been bombarded with advice along with my own meticulous researching every single topic about pregnancy, breastfeeding etc....I might be the first one to tell you this but sleep when the baby sleeps is such a crock of shit! My son is almost 3 weeks old and I am struggling to take care of myself....I have been putting him first for everything....thats what we are supposed to do as moms right? Well I am struggling with getting my milk supply going bc I'm not eating great or drinking enough water or getting enough rest. Everything I read is so damn conflicting....my boobs are getting sore so I'm afraid I'm getting clogged ducts so here I am freaking out pumping at 1 am when I should be sleeping while my son is asleep. My baby has quite the apetite and has been drinking 4 ounces since he was 3 days old and my boobs seriously cannot keep up. "The only way to make more milk is to nurse or pump every two hours!"...tell me how am I supposed to get any sleep if I have to do that and if I let it go too long without nursing or pumping I could get clogged and end u with mastitis. Once I get him fed and changed and back to sleep...then pumping and then trying to take care of myself its time for him to wake up again....or then there are times when he fights sleep or has gas and will literally be awake for 3 whole hours between feedings. I have help from my mother in law but I am the only person that can comfort him and its just hard sometimes. I really needed to get all that off my chest. I knew this wouldn't be easy it just seems like all the advice in the world could never help me with this.
