Anybody else not make it as a Stay at home parent?

I'm completely heartbroken that I have to go back to work. We just couldn't make ends meet with just one income. I never wanted to be a stay at home mom, I actually used to scoff at it. But when my baby was born I wanted to spend every minute I could with her she grows so fast! I return to work after I had her and was delighted when my husband got a Job that payed enough for me to stay home! After about15 months, and a lot of unexpected crazy things happening, we are behind on rent and other things and I have to return to work. I'm heartbroken, Has anyone else gone through this, and how did you cope?
