I'm sorry Anna...only thing that will help is time...I know it sounds dumb but it's true...hang in there it will get better...
I hate holidays because I am never so lonley as when a day such as today rolls around and if I'm lucky I'll get a happy valentines day.. it's worse when you have someone, who does nothing because there is that expectation (most ppl do stuff for their mate, right) that never happens ever..being so taken for granted that you are no longer a person to love but a person to use.
Why the hell do we put ourselves through this stupid thing called love??
