I'v been with my husband for 3 years now. I'v never worried about him apart from the fact that he couldn't seem to hold a job. Something always happened, he got extremely angry and quit etc..
Then I noticed that sometimes he would have major mood swings, if he couldn't find something he would get so angry and start throwing things, or if he was tired and had to wake up etc.. He always apologized after and I just shrugged it off as hot headed as he's never angry at me.
Lately, more and more I'm worried about him. He acts impulsive. Spending money we don't have, not attending to matters that need to be dealt with financially and things like that.
I thought maybe it was immaturity, but he really wants to do well, he has good intentions but his moods hold him back.

He works in the oilfield and left to work last week. Every night he has been up all night upset and crying. Calling me and telling me he misses me and the kids and having horrible dreams keeping him up. But once he gets to work and is busy, he feels fine.
This morning he woke up, said he went off the handle, packed up his things and quit and is coming home. He was crying on the phone, I started to cry as we cannot afford to not work.. And he told me he was going to shoot himself or run the car into on coming traffic.
I calmed him down and told him to come home and that I would like him to see a doctor which he agreed.

What could be wrong here? I know he needs help, this might be the wrong section but I would really love some input on what our next step could be .. I just want to help him.
