Good Grief!

Why do I even bother giving my time and attention to people who do not care for me?
Why do I even assume that they would, even just for a minute, stop to think that I have my problems too?
Why do I even try to be empathetic to people who do not have the capacity to understand my feelings and other people's feelings?
People want to be understood but they don't want to try to understand others. It's human nature to be self centered specially when depressed but how long can one remain depressed and be self absorbed without exhausting the goodness/kindness of others?
Something was said to me that obviously was passing judgement on me:

(6:37:46 AM): i dont know why you cant understand me
(6:51:00 AM): how would you undersatnd how not to worry, youa re good in not thinking and ignoring and not worrying
(6:51:05 AM): that is what i admire abt you

These statements were not flattering and they were said to me at 6AM. The classic example of acting without thinking, which was how we got into the discussion because the said person acted coldly then regretted it and started freaking out after realizing the damage that's been done. Not my fault that you acted that way so don't give me grief over your actions and words then say "I don't know why you don't understand me, I don't know why you're offended."
