You're the carer for your husband, right? Caring is really tough, I know (though in this situation I'm the caree), and it can feel a very lonely place. But there is support - here for a start - so don't give up. i can't speak for anyone else - but I won't think worse of you if you moan. i won't even think you're moaning.
Do post, and between us we'll see if we can help.
Take care - we need our carers!
