That sounds terrible, doesn't it?
What you're describing does sound like what others of us are going through. I don't know for sure, but the way to treat it is probably similar. Here's my advice, which you might or might not be able to use.

I suggest that you find good support for you. By good support I mean people who won't support weak stuff like, "Yeah, just divorce him, you deserve more." If that is so, it is by far the best to find out from the heart of you and it's nobody else's business. But first, you need support for your best side. You need a good church, or group, or the best people in your family.

Don't complain about him to your family--they'll hate him, and then when things are better they won't move on.

You can't change him, either by trying to kick his butt or by being sweet. But you can find the best part of you. In the long run, this is good for you and if he comes back, he'll find a better you. But if he won't come back, you'll have learned so much.

Antidepressants are good. They let your brain register a sunnier outlook. I've used them in the past. (I'm not doing it this time because I want to be transformed. I also think it could be thyroid. But if this lasts much longer...) Antidepressants are not a crutch. They might help that 'stuck' feeling.

Look at the nutritional picture. Un-nutritious food and a lack of essential fatty acids can mess with your brain chemistry and your hormones. Look for the fiber, vegetables, et cetera. He might not be willing to eat them, but vitamins and fish oil capsules are easy to do. Get the vitamins from a health food store and not the grocery store, because they are in a more usable form.

Anyhoo, Sorry for your troubles.
