I feel like no one cares anymore

Dear you (as in anyone who is reading this),
I feel like if I disappeared right now that no one would care because everyone I thought loved me now hates me with a passion. I feel like if I died right ow that everything would be better for everyone including me because for the past month I feel like I make nobody happy and make everyone else have a living hell of a life. I don't understand why people have to be so cruel to someone who only wants to be called beautiful, or nice, or even hear that someone loves me. the only life I have right now is my music and even that makes me feel badly because every song reminds me of why i used to be happy! I don't get why I have to feel this way when the only thing I want is to smile! I have been faking a smile for about a month and i am getting sick of waiting for things to get better! I was in a relationship i thought was perfect, which turns out it wasn't but i still care about that person with everything I have and it confuses me on why I have to go through all this and why i cant just full on smile and feel like everything is alright!
Sincerely,
A person who is now crying and pissed off

Hey, I'm so sorry you're struggling so badly!! When I feel horrible and depressed, I try to sleep it off, then change my environment, get some sunlight, and help others. If I still feel awful, then I need a med adjustment! Hope you feel better!!

You do matter. You have enormous value as a person, I want you to know that. I also want to say that I care and I love you. You are hurting right now and need support, I hope you can find it, I know there's tons of support on here and I'm here if you need me. But don't cut your life short, you don't know where it's heading, I know it feels unbearable now and like it'll never get better but there will be a time you will truly smile again and I want you to be able to experience that beautiful smile I know you must have.
