Maybe you're going through an especially difficult time right now and I can empathasize with just wanting to run away from it all and wanting everything to just stop. However, there are too many individuals out there who love and care for you deeply, and without you in their lives, they would be utterly devastated. You mean a great deal to at least one person out there, so play in your mind that you're going to keep going on in your life for their sake - that their happiness is more important than yours, and the only way to show your love for them is if you keep fighting.
This is what has been working for me lately. I don't know if it's the best or healthiest way to think, but that's what has kept me going every stinkin day.
