Maybe the answer is you and your husband both go inpatient and your son stay with relatives or friends until you are stabilized. You just cant keep going the way you are, you are running yourself ragged trying to keep up with both of you. Its not right and its not fair for all of this to be your burden. Your mental health is just as important as his, you have a son to think of as well, who is watching both parents implode in front of him. Both of you need help, now. Thats my take on the situation.
