Keeping up with a husband and three children are not simple stresses--dealing with four personalities and their schedules (and some of your husband's behaviors stress you out--it is not unusual for many husbands to leave most of the household chores to their wife and it is not right if you are also working) is not an easy task. Do you think you are having an episode that will run it's course if you can manage to not a make any terrible, impulsive decisions that make your situation worse? Do you have a therapist you can talk to? We can start ruminating about all the things that are wrong (I have been there) and all the thinking makes it seem worse (not that it isn't a bad situation). Whenever you want to do something like run away--either sleep on it or plan it for a future date so you have time to really think about whether it is right or wrong and get feedback from others. I agree with Wild Coyote that you may not feel right about leaving your family while you sleep because it will hurt/traumatize them. That might create guilt later that will make you feel depressed.
