where's the reason?

I believe that everything, whether good or bad, happens for a reason. I'm fighting with myself to accept that today. I am strong today because of the events of yesterday. But is there a limit? Must we be eternally tried, only to become tougher and tougher? Is it not possible to become too hard, too tough, too stoic? Where's the reason in that? Being out of touch with people because you just can't feel emotion anymore is not a desirable goal. Most days, I am undaunted because I've been tried so much. Once in a while, though, I stumble.... Today is one of those days. I blindly put faith in people. Everyone is good until they prove otherwise. Of course, some will prove themselves unworthy. What I fail to understand is how most people eventually show me that my efforts in cultivating any sort of relationship with them were wasted. How can nearly everyone be...bad? Am I just so out of touch with people that so many relationships I've had end on such bad terms? I want to think that everyone has friendships that just don't work out, but if everyone does, then why don't they become as disappointed and/or cynical as I do sometimes? Do I just not see it?? If it happens to others nearly as frequently as it does to me, at least one person I know must be going crazy at all times! But I still don't see it. Maybe I'm just really weird, really different. My faith in this world has been slowly seeping away since day one, but days like today, I lose so much more.
