You could've been getting trolled

Don't worry. It might have just been people with different tastes that read and commented on it, or, if you truly are bad, most people start off not good at things and then get better.

That's awful OP. It's hard not to get discouraged. My novel has been rejected too many times to count and I just got a short published. All you can do is edit, revise, and try to move forward. I'm curious about the piece you put up though and I give very considerate critiques :)

Get involved in another hobby, and when you have a kid make sure the kid knows when he/she is good at something, or bad at something. Trust me, (and you should know now) that knowing things you're bad at will help later on

who cares you tried your best don't let people bring you down. if it's good to you it's good. you ahead and write your heart out

Don't beat yourself up about it. If you like writing just keep at it and it'll get better.
