Hi there, (we don't really know each other but I just read what you wrote and I thought about leaving a reply here)
Seriously I've never talked to you and I've read a lot of your stories you posted on a facebook's group. I really want you to not stop believing in yourself. I, myself, delete my fanfictions all the time because I feel they were full of mistakes/didn't get the response I wanted; but I would never stop writing.
Either it's singing/writing/dancing it's a part of you, that can never be separated. Don't lose hope, and dream big. There is no great writer/singer made it from the first time. Everyone started from the bottom and took their mistakes as a motivation rather than a sign of failure. No one is perfect. Be always proud of yourself. Life is short so don't care about being imperfect pursue your dream. Satisfy yourself before the others.
Have a good day, sweety.

SOBS
I'M A FAILURE TOO
I CAN'T SING
I CAN'T RAP
I CAN'T DANCE
I'M NOT PRETTY
I CAN'T WRITE EITHER
OR DO ANYTHING
honestly, all i live for is food. and eating. it makes me happy.
besides, you're still young. you never know what might happen. it's not like you're a grandma or something.
SOBS LETS BE PITIFUL TOGETHER

:( It's ok. Just let it all out. (Pats you in the back)

But you know, I don't think you're a failure :) I think you just need time. I hope you get your hope back :) Because remember when I reviewed your story? I said that I enjoyed it and that it was unique ^_^ You were good at that! And I don't really know you, but I think everyone has things their good at :) Like expressing your feelings in this blog. You're good at it too! I can feel your sadness even though we're apart.

I don't know if I have the right to say this, but be hopeful :D You asked why you live? You live to experience life ^_^ In the down times and in the up times, it's life you live all the same. And even though the sad moments are when you feel worthless, you'll find out that there are people telling you the opposite :D You are not a failure.

You're a good singer, a great dancer, and a brilliant writer in the making! You're in your way there, but the road is rough. But please know that as long as you keep a positive view of things, you'll somehow get to enjoy life as the journey goes on :D

I don't know if this helped, but I wanted to comfort you :D God bless you! And I hope you feel better soon.

Everyone makes mistakes. Cho ana mzeblaha f kolchi w wakha hakkak peaaaace. I in writing, dancing, singing, studying (hadi ana kanghech fiha 7it I used to rank 1st w daba majabch llah), douran chghal... kolchi gha 3ala 3la lmojtama3, walakin 3adi daba nt3lm chi nhar lol
We never learn without making mistakes, so don't be sad or disapointed, I'm sure you'll become a better writer/dancer/project maker (I doubt you can improve the singing part especially ila 3ndk sot bachi3 b7al soti but u can rap :3 )
Just practice more and I'm sure u'll improve a looooooot
And everybody has something they're good at, just try to find yours and learn to love it and give it your all.
(I didn't find mine yet but I have a feeling that I would ... soon nshallah)

;( you can do the things you wish. Though if you look deeply into those wishes, you might find out, it might not be the thing you want. Maybe you want something else. I wanted to be a musician, but, I figured out learning language is my wish. Maybe,.. You need to be more of a reader? Not saying to give up. But as you read fics, you will get better, if it is truly, your wish. :)
