lost it with the wife this morning, she stormed out off to work, just feel so alone and angry.
I think given your circumstances mate, that she will forgive you for any mood swings.
I don't know what meds you are on mate, but if you're not taking a sedative, I'd strongly recommend them. There's a lot of misconceptions about sedatives - they turn you into a zombie etc. But used correctly they are wonderful. They'll take the edge of the anxiety and hopefully counteract the anger and fear that you're feeling.
Give her a big hug when she comes home mate x
