Why can't everyone just be Happy?!?

I just wish people would understand what I want and how I feel. When I try to open up, they make me feel that what I have to say is not important and will just try and blow me off, but when they need someone to talk to, who's the first person they call, that's right me! I have pushed so many of my own problems to the back of my mind because I do not want to burden anyone and I have gotten to the point where if I am not able to release some of my feelings and unresolved issues, that I just may have a mental breakdown.......Lately, because of one special person, I have little by little been able to vent. I know I can count on her to listen to my every word and that she really cares. By the end of our conversations, I usually feel at peace. This is something and someone that I have needed for so long and I couldnt be happier. But why is it that others are not happy for me? Why are they jealous of my relationship with my friend? If they would treat people the way I treat people, then maybe they would have special bond with someone they say they care about. Dont try to bring me down because I wont let you, I am finally begininng to feel that I am worth something and I refuse to let anyone take that away from me.........So sit up and Listen.........I am HAPPY and you should be happy for me!!!!!!!
