I concur with what Liz said. Also they say that exercise is supposed to be helpful, some studies have shown that it can be as beneficial as medication, so Popcornbird's suggestion of a walk in the park has merit too. And as Soapet mentioned, make sure you get a proper diet.

Your husband's loss of a job and health insurance could certainly have been a trigger to your current episode. I've experienced both those situations and it worried me silly. I am so very sorry that all this is happening to you right now. I do believe unloading your feelings here can be a bit of a help, and that is reason enough to come and share as often as you want. There are lots of folks here who genuinely care for you and care about what happens to you.
