Why Is This Happening To Me

This is my last year of high school, I thought this was going to be the best year of my life but its the worst. My best friend desided to make new friends this year and I didn't have a problem with it, untill she said she didn't want to be friends anymore, I don't know why but that's what happend. I was hoping this wasn't going to be a long term thing but it is, and now she talking about me saying stuff that isn't true at all, I know I need to stand up for myself and I will. I just feel so alone right now, like I have no one, I can't even reach out to my mom right now because she doesn't understand and I know a lot of teens say that but this is true, she doesn't want to listen to me. She always puts her own thought in her mind and hears what she wants to hear and not even close to what I say. I give up on trying to be nice, trying to fix things, trying to tell people about my feelings. I tried of the drama and lies and the trust issues I have with people now. I just want someone to talk to that will listen to me, for once and hear what I have to say and not what they want to hear and not make up things about me.....
