Newborn Nightmare

6 weeks in and I have never been so miserable in my entire life. We've been through gas problems, reflux, and now just screaming for absolutely no reason. We have switched formula, switched bottles, give him prescription Zantac, Mylicon drops, gripe water. If I'm lucky I get maybe 3 hours of sleep a night. My husband is completely and totally worthless. He can't do anything, doesn't even try, all he wants to do is play on Facebook from the second he walks in the door until he goes to bed. I get up with our son all night every night. I never get any sleep during the day because I have to clean the house, do laundry, sterilize bottles, cook, etc. 

The thought of ever going through this again makes me want to get my tubes tied, like, yesterday. Everyone says "oh it gets better!" But I'm finding it very hard to see the light at the end of this very long tunnel.
