hi kris. i kinda been there but on the other side. i stay home and take care of our son while my wife works. im bipolar and i get depression like that off and on, don't wanna go nowhere or do nothing just want to hide all the time and can't sleep. theres probably different reasons for everyone why they get those feelings i'm sorry but i don't know what to say about what will make your husband feel better but when i get like that i don't even know how much it hurts my family until my wife tells me that she needs me back out of my head. i've been in therapy for years and its always been talking there with my wife coming with me that gets me back to reality every time. maybe you can get him to go when he knows how much it is hurting you for him to be like that. good luck
