He went out of work for 3 months and just recectly went back.  He is still blaming his job for making him this way, which I know is not true.  We have 3 children under the age of 7, and are starting to ask questions about daddy.  Some of the doctors I've spoken to about this told me that they need to be told that daddy is not feeling well and we need to help him get better.  What do you think I should say to them? 

This started to affect me for quite some time and I've been crying for 3 weeks every nite.  I feel like I can't be around him anymore.  My household is so tense all the time.  He follows me into every room I go into, pacing, picking at his nails, and at nite in bed, he sometimes sits at the bottom of the bed staring at me.  He is now staying with a friend because I cannot live this way anymore.  He's been in a partial program for 12 weeks, different phsychiatrists, and therapists.  He doesn't seem to be helping himself.  The only way he'll do something is if you tell him to.

What should I tell my kids?
