I just got home from my last choir concert and it was a complete disaster

I don't think I've ever had a performance that bad ever

my mom and bother didn't like it because it was too long so they were just bored out of their mind :/
During our dance the song got cut off and we had to stop and that ruined it for the girls
And lastly this made me upset the most

my friend didn't show up I don't know if I didn't see her or she just didn't come but I looked out in the audience I couldn't find her

so she didn't show up and I'm crying right now
I was hoping to see her and she said she was going to show up but she didn't and it completely brought my mood down I had cupcakes for my friends and I ended up making them for nothing

And my mom didn't even care that I was sad she was like "Well she couldn;t come so what?" STFU!!!!She is my best friend and she always makes me happy gawd my family just doesn't care!
everything is just horrible right now I feel like I'm alone and unwanted
I won't smile anymore now I need a hug right now
