Feeling depressed

I feel just disconnected big time. I've got a 5yr son who takes up any energy or free time I can call my own. If not him my husband demands time even though I basically spend time " by" him cleaning up my messy house. So sick of being the only one caring that we don't live in messieness and clutter ughhhhhhhhhh. My friends are all too busy to make much time and I also work part time. Feel like curling into a ball and disappearing just to find a moment to think or feel something. Need advise or a friend
