Frustration

I'm to my breaking point yet again.  I just do not understand people.  How can some people be so inconsiderate  and do things that are only benefiting themselves.  I am trying to stay positive and work for the Lord but it becomes very hard when others know I will do the work and they try shoving other tasks they should be doing on me.  I also hate when people lie about the smallest little things although everyone knows they are being deceitful.  BLOWS MY MIND... I'm not say that I am perfect by any means but when people throw things onto others just because they are too LAZY to do them themselves even though it only takes 5-10 min. just makes me not care.  I also hate when people think they can walk all over others because they are easy to intimidate.  Then when I stand up for my friends I get yelled at. hmmmmm..... does that sound right to anyone??  I feel that certain people come to me not only to vent but because they know I will do something about the situation.  Trust is something that I don't come by often around here.  For those who truly know me know what I am talking about with all of this.  Who knows how much more of this I can take because obviously these people will not change their ways and I am to stubborn to change mine.  But I feel like I am right I was raised the right way.  Thanks Dad!
I hope you enjoyed my venting/thoughts.
