Do you have a current therapist and/or psychiatrist? Primary care?

If not, that might be your first step, at least to get the ball rolling. I don't know where you live or how difficult it is to get in the door with any of them.

If you have insurance, they usually have a number you can call (or a website to try to narrow down providers who are taking new clients/patients).

Also, what about significant others or family members? I would get them involved so they can help take care of you and the kids.

If all else fails, going to an ER with the expectation you'll be admitted somewhere might be your last option.
