Today wasn't one of the best days i've had

[Deltron]

You really need to stop thinking about the situation. The more you put thought into it, the more it will sadden yourself.

Try something that will help keep your mind off this. Exercise will release your stress, and ultimately make you feel better.

I know how it feels, and there is not much you can do to solve the problem. Move on from this, and find another girl; there are plenty out there.
