I Sat Alone And Cried

Sometimes when I go visit one of the places I grew up I will get an overwhelming sense of sadness or utter failure and will go off by myself and cry profusely. I really don't have anything to cry about, it just hits me hard. I can just be looking up at the stars or looking at pics of me when I was a little kid. I don't know if it's a feeling of not fulfilling something or a sense of sadness for moving away and thinking that my life would be better if I had never moved away. Inevitably someone, friend or family, will find me and try to cheer me up. At that time I don't want that but I feel some sort of duty to make them feel they are helping me. I have no idea why the sense of sadness hits me... but it does. It's not always sadness or failure, sometimes it's a sense of peace but ends up with a cry
