Returning to Work After Baby... I can't.

I am hardcore struggling to return back to my career after baby. I get that it is what it is, but my position is extremely demanding and is 50-60 hours a week. I didn't spend 3 years (and thousands of $$$$) trying to get pregnant to leave my son at a daycare. The more I think about it, the more I can't do it. I am being offered a work from home position outside of my current, very-stable, company. It's a little less money... a small risk... but in my heart of hearts, I feel like I should take it because I want to be close to him while he's this young. I basically am hoping for some encouragement to take a leap and follow my motherly intuition. My husband has a great career... I've always been a career woman, but now I'm a mother and I just... I just can't go back to working these hours in an office. Can someone give me a boost of hope/confidence?! Please... any success stories of not returning back to work and staying with baby? Anyone else having this crazy struggle??
