Heartbreak is awful and I promise you, even though it sucks, you will have to go through a lot more of it before you find "the one". Also, don't settle for someone who makes you feel horrible or chase someone that doesn't give you the time of day because I promise you there is someone out there willing to give you the world. You maybe just haven't found them yet :)
Heartbreak is never easy, but eventually all of the pain will be worth it. Just give it time.
