Can't sleep

Can't sleep. Me and the husband have been arguing so much lately. I wish we could be happy again, like we used to be.
I'm sick of being so sad all the time.
I deleted my Facebook account. People got tired of me complaining, so I just deleted it. It sucks because I had a lot of friends on there that actually made me happy.

I love my son so much and I hate this for him. His mommy is constantly crying and yelling and he deserves better than that.

Don't know what I'm supposed to do...
