Nothing weighs lighter than an empty promise

The above title might not be suitable for the post as she has not made any promise. Feeling disappointed just like when someone giving you empty promise. When you hope for something but in the end it turned out nothing. I  am neither angry nor sad, i just feel disappointed. Why are you so easily influenced by someone and can't you stand with your own decision? Friendship had given me a mass of disappointment. I had given you my trust and yet you repay me with disappointment. You think and care about her feeling, how about mine? When i need help, nobody cares. I need to stand on my own feet and think of another solution by myself.
