Weight loss help!

Ive struggled for the past few years with my weight and only really started putting it on when i broke up with my ex. I weigh 14 stone 12 pounds and really want to loose weight because most of my friends are skinny with nice figures. Can anybody recommend something i can start that has worked for them? I find if i start exercising and dieting i get bored after a while and its pointless :( any advice at all would be useful! :)
