Gosh I would finishing the many renovation projects we have to do to tip top standard; nothing flash but quietly good quality.
I would buy in help with cleaning, cooking, shopping and driving.
I would give the 14 members of my family and my godchildren some substantial sums of money.
Give money to the Trussel Trust, the Lemon Tree Trust, the RNLI, the local rescue helicopter, and try and fund a homeless charity for a decade.
I would take on some more rescue horses and buy land to house them. And maybe a bit of forest.
Maybe a tiny apartment in London.
I am not bothered about clothes but I would love to buy one lovely ring and a pair of earrings to wear all the time.
And finally I would buy some paintings from an artist I admire.
It's cheered me up just day-dreaming about it! 
To get back to reality, I know someone who has lived on a trust fund all his life and he is quite a troubled person. It hasn't done him any favours shall we say.
