Please know there are much better things in life than being lonely or liked or bitter or mean or self-concious.
We are all full of shit.
Go love someone just because, I know your heart may be badly bruised, or even the victim of numerous knifings but it will always heal, even if you dont want it to it keeps going.
There are the most fantastic, beautiful things and people out there, I promise.
It is up to you to find them.
