Why?! What?

Lately I've been feeling like no one cares about me. I'm easily replaced or forgotten and I don't get why or what is it about me. I had this girl who I thought was my best friend, we were friend for years and I was there for her through thick and thin. Her and her longtime boyfriend broke up and slowly she wouldn't answer my text or reply with a word or two. Then, nothing.... we don't talk anymore. My cousin who I was really close to was kind of doing the same and it just seems like I have to reach out to her all the time. I thought we were close but maybe it was just one sided. Should I talk to her about this? I'm confused! I just feel alone and easily forgotten.

Forgot to add that my friend got a new boyfriend and put a post about how she's leaving some of us behind. That's why I feel like..was I not worth anything to you?
