Apathetic Resilience

When does resilience turn to being apathetic? My cappy gal friend has become so apathetic to people, relationships, and good things in her life that breeds negativity. I keep telling her to be grateful for the little things going right, and she states that she is a resilent person. I told her no, she's becoming apathetic and can't see a good thing when it comes her way!

In the past when I've been through such trying times, I just didn't care anymore. I let it go, and I didn't give a damn. Does that mean I'm becomin resilient or just apathetic? But then I realized I was lying to myself and I really did care.
