by your DC just on the walk home from school?
i'm having one of those - i've just broken down and told DH i feel DD is sapping the life out of me 
she wet herself in school again, she has a 'tummy ache' and won't talk to me at all right now. she's lying on the sofa under her blanket watching TV.
i've had a lovely day without her, met a friend for coffee, walked in the sunshine and now 'boom'
i feel terrible for it - DH gave me a huge hug and just held me, i'm not sure he understands really but he didn't say anything, just hugged me
i don't need any replies, any advice, i just needed to get it out to people who (hopefully) understand
i've tried 'messing about' on jokey threads elsewhere on MN to cheer myself up, but i'm still crying
i hate days like these
