I just had a couple of days without DH, as he had a business trip. I started on anti-depressants last week so I was pretty worried about coping with the DCs on my own.
But I did! And actually did more housework than I normally would. Had a couple of visitors (my dad and some friends) which really helped.
Maybe IABU - sorry if I am, I know loads of people cope with being on their own a lot more - just to me, it's quite an achievement that I didn't crumble and end up sobbing down the phone to DH!
