Okay I just need to vent

A year ago today, my BFF's grandma passed away. I decided to do something nice for her to show my support. I went to the store last week and bought her a gift, even though i have a broken ankle and it was really hard on me. I told my mom that my friend was going to come over today. I also asked my friend if she would ask her parents if she could come over. Of course, both my friend and my mom forgot. My mom scheduled other stuff for me to do and claimed that she didn't know that my friend was going to come over (even though she took me to the store to buy her a gift). Then my friend forgot to ask her parents. I reminded her today, and she asked but they said no. For no reason. She was going to bike over here so that they didn't have to drive her, but they still said no. This just really pisses me off because I'm going through a really tough time but i still though of my friend, but when I tried to do something nice for her, I got completely shot down FUCK MY FUCKING LIFE!!!!!!!! I FUCKING MATTER TOO!!!! IT ISN'T ALL ABOUT YOU!!!!!!!!!
