:hug:I agree with Emz you need to take time for yourself,even if its just 20 minutes a day sat in the bath or in the garden, or a quiet place where you can regroup and process whats happened in your own mind.Its very difficult to support some-one through their grief when your own is so raw as well.
So spending time here, creating an outlet for yourself, writing your own feelings down,will help you be stronger for your husband.
I lost interest in work too but i had to keep going and going through the motions,interest does return eventually but i think when it does, what comes with it is a new attitude,so many of us define ourselves through work. If you get introduced to some-one "what do you do for a living" is the standard question, and our answer puts us in a slot - person of further interest or not so we put ourselves in there too. We may or may not enjoy the job, but what has happened brings it home too us that life is horribly short so i need to do more, to make sure i live it and not just work my way through it. Some people change their job, or direction because of that, others change hours or location to free up more time - For now while everything else is going on, going through the motions is enough.
