Wind down

How do you wind down after a bad day at work? I work from midnight to eight, I have a wonderful boyfriend, a cat and a dog. I get home from work frustrated or upset about something and get even worse when I feel like I have a million things to do when I get home, it just adds to the stress level. He is wonderful about pitching in and helping but he works 12 hour days and it's a little harder for him to help out. I get home at 830 and try to lay down by 930 to get 8 hours of sleep but days like today... I'm all worked up from a bad day and wide awake... Please help!!!
