I wish someone would just kill me.
Poor Fiona! Try to get through the next week or so somehow; it won't be long until you're at university, where things will be a lot better.
It's not uncommon for mother/daughter relationships to hit rock bottom at around this time, and it doesn't necessarily mean that you'll be at loggerheads for ever. I'm sorry that you and your mum seem to be hurting one another so badly at the moment, and hope the rest of the week passes quickly for you.
I'm having a Very Bad Week. I've just found that a close relative's house has Dry Rot. - The living room floor fell in. And this is something not covered by Buildings Insurance.
Oh dear, what a dreadful thing to happen! I hope no-one was hurt. You need to get the house surveyed by an expert asap, as there's no telling how much of the woodwork will be affected. How old is the house, and is your relative able to stay with family or friends in the meantime?
