DD (8) drives me mad. She isn't a unkind or naughty or anything like that but she is just SO annoying and difficult to to be with. She never stops talking (almost literally, way worse than any other 'talkers' I've met), she fusses over everything, she has no patience at all with her 3yo brother and can be quite mean to him, she argues with us constantly, I have no authority over her, she constantly interrupts... I could go on. It's funny, when I type it out it doesn't sound that bad but honestly, she is a nightmare to be with. She's far worse than any other children I know. It's not just me who struggles with her either - DH and my parents find her very hard work too and my mum really worries about what we're going to do with her. She has me in tears several times a week and my patience is shot to pieces (though part of that is her brother's fault as he's very hard work too!) We have a big arguement at least once a week and we both end up in tears and we hug and try to come up with a way to make it better and we both make promises and things start to look up - but then it all starts all over again a few days later.
I don't spend a lot of time with her because of this and I wonder if this may be part of the problem? If she had more of my attention I wonder if she would calm down a bit, or is this just who she is at this age? She wasn't always like this. Also, I am a highly-strung person too (very short fuse, shout a lot etc.) so maybe I've just taught her my behaviour 
She always wants to play on her DS/Gamecube/the PC and, because we find her so hard to be with, we let her
. I know this is very wrong. Frankly, I dread the idea of spending time with her and I hate that I feel like this. Does anybody else feel like this about their child or am I just a horrid mummy? :( And what do you do with your child if you don't actually want to do things with them?! We used to be friends - how can I get our relationship back? I joke that at least we will get a 2-person discount on therapy but I fear that we are actually heading that way
