Glad it went well SallyG

I just wanted to say about the clutter - I agree with pepperminty this is not important at all!! Do you want to be remembered/thought of as a woman who kept/keeps an immaculate house (god how boring!) or someone who painted/collected pictures and was well read ( if the books and art-work are yours)?
What is the clutter anyway? Is it rubbish and dishes etc that need clearing away? Is it stuff waiting to be sorted? How you deal with it depends what it is. Is it preventing you/your family from carrying out normal household tasks? If it's rubbish/newspapers etc then yes your daughter can help tidy up after herself. All my children (I had four) had jobs to do each day as part of the household and an extra job at the weekend eg hoovering etc. They changed their sheets and by the time they reached 16 were ironing their clothes ( except I did school uniform). I was working while they were at school so they had to pull their weight.
I feel your daughter needs to realise also how unimportant it is to judge people by their houses and things and not to be ashamed to bring people back. Do you welcome her friends when they come or do you communicate anxiety about the state its in? I bet it's not that bad - our house is full of clutter

. Anyone who keeps an immaculate house is either rich (got a maid), very poor ( hasn't got much stuff) or doesn't have enough interesting things to do!!! Exceptions of course if there is someone with disabilities in house who might trip over things left about.... also toddlers who might swallow things! Basic hygeine is important too!
Does she have a room of her own that she can do what she likes with - and can her friends go there? Does she have run of the kitchen when they come - to make coffee etc/snacks - provided they clear up of course.
As for Cribb's Causeway - heavens that place would give me the heebie-jeebies. It's probably our nearest big shopping centre ( it's about 65 miles away). I've only driven past it and through the edge of it on the way cutting through somewhere and it was
horrible!!! Once I had to drive past in early Dec and the queues to get into it stretched right out onto the M5. Aaagh! A monument to rampant consumerism. I can see it's a treat for a 14 year old to buy a new item of clothing or two as a treat but educating her about sustainability in the world while giving her a few selected treats/pampering - will go a long way.
If you're feeling rough. Can you sit down at the weekend and direct her in some of the clearing up if you don't have the energy, and then reward her with some quality time together or some other treat (I don't mean bribe her either!). or you could legitimately pay her (with treats etc if you can afford it) in return for doing a bit more. My kids' pocket money and later allowance was dependent on their doing their share of jobs (it sort of went out of the window a bit when they got part-time jobs but by then they accepted they had jobs to do).
You have not let her down at all. I am wondering why you feel you have - because you can't spend money on her? She is 14 so should be able to think about getting a Saturday job to pay for extras and gradually increasing hours as she gets older. It's a truism to say that love isn't about spending money!
Do talk to her about values and priorities from the earliest opporuntity - and she will grow up with a better understanding and appreciation of what's really important in life.
I hope you will take this in the spirit in which it's meant ie helpful and re-assuring rather than critical
