Hearts are fragile

So, you think you know your heart pretty well? You see guys you fancy and then your World is turned upside down when they tell you they don't like you the same way back. It crushes you like being trodden on. It doesn't exactly help your past invades your head with all the names you've been called in the past and the EXACT words your Gran said to you the day your Granddad died, when you were only thirteen. I guess no-one told me how cruel love could be, or how being bullied since you were three could mess up your head.
