SAHM feeling alone?

SAHM or wives, do you ever feel super alone? Almost like you're going through everything by yourself? I always appreciate the work my husband puts in for our family, but I can't help but feel like I'm a single mom except for a few hours of the day since he works so much. I've become very depressed and I feel like I stare at walls all day, waiting until he gets home, and when he does he's tired, and it goes back to the same feeling.

How do you cope? How do you stay sane through it all?
