It carnt be helped in my house i dont have a dining room just small front room and kitchen no one in my tiny house gets personal space it's normal life for us
It can't be helped for most/many families Crazymad. As you rightly say - it's just life!
All of these people accusing OP of having too many children when she can't give them what they need etc, and all this "Why don't you sleep on the roof on a specially constructed mattress and the girls can have a room each and put a glitter ball in the living room so your teenage DDs friends can hold special parties and also a gazebo for them to relax in outside etc " - absolute rubbish. (I am aware that these exact words have not been used - I am exaggerating to show how ridiculous some suggestions are)
OP's DD is a teenager - she is at "that age". I agree that her hormones will be driving her crazy. Whatever OP does, it will not be enough - there will be something fr her to moan about because that's what kids of that age do. The world is against them; everybody else's mother* is more generous than theirs; their friends can all stay out till all hours and their parents trust them not to get abducted; they all have better clothes/holidays/personal possessions. THIS IS THE WORLD OF THE TEENAGER!!!
Puberty is HELL - for EVERYBODY.
OP is doing nothing wrong - she just needs reassurance and support that her daughter isn't a witch in child's clothing, and that she herself is not being unreasonable - OP - she's not and you're not. OP is doing the best she can in a not-ideal(by many people's standards) situation.
We don't know why she recklessly decided to have a second child when she couldn't look after them both properly (as some people have accused her - what rubbish) - we do know that she is providing a safe and loving home in a good area where both her girls have a chance of good schools etc.
There are people here who seem to think that a girl's life should be all ponies, ski-ing, designer clothes and sleepovers, and wouldn't it be wonderful if it was - but it's not! Most of us do the best we can for our children, and that doesn't mean giving in to their every demand - all that does is make them selfish and entitled.
And not providing each child with their own space doesn't mean we don't love the very ground they walk on either, because we do.
*There was a time, when if I had ever got the chance to meet this mythical "everybody else's mother", I would have beaten her to death with her own halo.
