I was deeply hurt ..

Do you ever have the feeling of being alone? I just keep on having the same feeling recently..I felt that the relationship which is just maintained by me has been changed. I don't know what's happening right now?! What's wrong with all of you?! Was it because of the effort which i put into our relationship not enough? Or maybe i am just the only one who is trying out the best to manage the relationship but you didn't? Sigh.. i was deeply hurt and fell disappointment !!!
