Living rent free in my head (old post I thought I posted)

I have a big heart.. Yes I am slightly mean and very discriminating in whom I left in my life... But when I allow people into my heart I tend to get very disappointing.. What I've figured out most people are selfish, insensitive,judgmental, and users.. They are so about them they never take the time to look up and see a sincere person in their life... Or they are judging you based on what they think not what they know.. So at the advice of my loving sister I need to stop letting these temporary people living rent free in my head and heart.. Taking her advice... Not kicking anyone to the curb but closing my heart and mind to those who don't deserve space...
