Grown immune?

Im sure everyone has felt betrayed before, felt like there is no way out of the emotional trauma, quite recently i have felt that way. I got myself so worked up at the sight of it. But now i feel like i have cried everything out, and i don't feel any pain but I'm not sure what to think. Its got me down so many times, maybe i have become immune. But for some reason, i don't want to be. It just seems odd accepting something that was supposed to be mine. I mean, I am one to hold a grudge, but only for good reason. And at this moment in time, I intend to keep it, but is it really worth it, if I'm feeling no pain?
