Don't spend every spare minute over the next three years at your boyfriend's house. He's a cunt who will cheat on you and loves playing games with you. Spend time at home with your mum and the dog. Your mum is a fucking hero for what she's been through and what she's coped with and you should just hang out more with her. In 10 years the dog will be 17, going blind, deaf as a post and just about able to walk- you should enjoy the 5 miles walks with her now while you still can.
In fact, just dump your boyfriend because he annoys you anyway so what's the point?! Don't waste three years on this loser.
Once you've done that please snog or shag Ben. He works at your gym, he's really hot, you fancy him, he fancies you- just do it!
When you're 19 you're going to go out with someone you really shouldn't. This is okay, it's what being young is all about but don't put out so early, string him along much further and get everything out of him you can. He's punching well above his weight, make him know this every chance you get.
Please stop buying cheap make-up. Either don't wear any at all because you don't actually need it or convince your mum to buy you some expensive stuff. What you wear looks cheap and nasty.
You've got a great figure but if you put some time in now when you're in your late-20s you'll have amazingly toned arms.
All them girls that you secretly wish you were a bit more like are going to massively fuck up and you'll be glad you kept your distance.
But, if you do nothing else from this list at all, please please please, invent Facebook.
