money

I need to help, whenever I get paid I literally spend it within 1-3 days and then have none left for the rest of the month. I'm nearly 16 so don't pay rent or anything but I just can't help spending. My parents have just shouted at me because I spent some money today but I was buying some xmas presents and they wouldn't understand what I was trying to tell them. As my hours drop in the winter I won't get as good pay next month but I don't need anything. Sorry it's long but any help would be grateful
