Am i happy?

i often ask myself this question whenever i feel like life never treated me well. it always come up whenever i want to do something but can not due to some circumstances, mainly because of certain someone. those are the times when i do feel that i can not be happy because my life is so restricted and i feel very trapped. when i want to go somewhere alone, i can not. when i want to be with my friends, i can not. when i want to be with my relatives, somebody else gets mad. there i always cry alone inside my car, parking somewhere before going home.. its pathetic and pitiful. i know i have a choice. i know i can change things but it requires great deal of courage to let go of the things that im already attached to..
