Hey there. Welcome. I know that you don't want to be here any more than any of the rest of us did, but I'm so glad that you found us for support.
Listen. Knowledge is power. Take some long, deep breaths, wipe your eyes and nose, and look up at the upper left corner for a yellow box. Take another deep, long breath. Click on The Healing Library. Get yourself a glass of water or other non-alcoholic drink and start reading. There is a lot of very good information there for you, that was written by people who have stood in your shoes and have survived. Even thrived. And you WILL survive this too. Read any other post in this forum that has a bulls-eye next to it. More good information.
And remember this and take it to heart. You cannot, CANNOT, take care of your beautiful children if you DO NOT take care of yourself. You simply cannot do it and you are the only sane person in your house right now, to make sure that they are cared for. You need to stay hydrated, eat whatever you can, and rest when you can. You need to place your needs, and then the needs of your children as a priority and your WH can take care of himself. He's an adult that has tried to fire you as his wife. You owe him no care at this point. You owe it to yourself and your children to focus on you and them.
Please keep coming back for support. As you're able, post a bit more of your details. I guarantee that there will be several people here who have stood right next to you, in your details. We're all here for you. (((hugs)))
