quick bit of back ground, I have mental health issues and recently feeling quite sensitive. I have short temper and don't cope with stress well and it triggers all sorts of problems.
all week dd 6yrs has cried everyday after school due to request I cant or wont do. its very often really but this week has worn me out. she asks to go to some ones house, I say no, explain why, she sobs. next day "can someone come to ours", I say no, she sobs, "can we go shop to get sweets", I say no you had some yesterday, she sobs...
today no tears straight after school but then an ice cream van drives past so asked to get one. I said sorry I don't have any change. so she wails!! "I haven't had ice cream for ages" stands there crying asking over and over, I said she needs to stop "wanting" and listen when ive said no.
then dd comes to me with a note 'please let me get ice cream then you can just get more money'. with a sad face. after going on 5mins or so I could feel myself getting annoyed, feeling uneasy. in the end I raised my voice and shouted explaining that she is sounding very spoilt and its not nice, not every one is rushing out getting ice cream or something along those lines.... 
I don't want to carry on being 'shouty' mum but dd goes on and on crying and more crying telling me I don't like her. I feel so tender most days I worry im just going to breakdown! over a flipping ice cream? I must come across pathetic.
im asking how others deal with their teary dcs and how they reply to constant demands. I wont ever win mum of the year award but im trying to be better
any advice thanks.
