he's going to need detox. Do you have anyone that can watch the kids for a little. That way you both can get back on your feet. Its not your responsibility to be strong for his mental health. Right now you both need as much outside support as possible.

If you don't have someone to care for the kids have the Dr write a script saying your children need day care until 6 pm and go after daycare assistance. Get them into sports if possible.

This is not your fault or his it's just a ****** situation.
