I Can't Not Care, No Matter How Hard I Try...Why Does It Seem As Though Others Can So Easily...Or Is That Just My Perspective That They Don't?

I've been witnessing lots of good things happening lately.  Seems as though so many of my prayers for others are being answered, friends are conquering challenges, I'm feeling better, and life is good all around me.  Yet I have this want to not care as much as I do for some people.  I am forcing myself to try not to care about or want to help the people I think I don't matter to...it's not working and I'm not so sure why I think I need to do this. 

It's not like an "X" boyfriend or girlfriend, someone who has physically hurt me or scorned me, someone who has stolen from me or anything like that.  I do know that I have my assumptions; have been lead by what many others have said in the past and what I have seen and felt; I feel as though what I refused to believe all along is now so visibly true.

Is that a reason to feel such resentment, anger, or hurt.  I feel confused and sad that I feel this way.  I'm praying that there will be a better understanding of these feelings so I can resolve them.  I don't want to feel this way, this is not the kind of person I want to be.
