Depression

I can't make myself be happy as a mother. I hate being a mom. I hate that I am ALWAYS SO exhausted 100% of the time. Maybe other women find it easier to function with less sleep or something, but I am always so sluggish and tired. Sometimes I will try to make a plan to do something and get out of the house but when morning comes all I want to do is sleep, so I put my son down for a nap and take a nap as well. I am chronically depressed and so irritable. My son is 2.5. I just don't know what to do with this. I feel like God's answer is "this is your life. Deal with it." I've done everything I know how do to and I'm just so so so so so miserable.
