Dont believe those bullies or anyone who puts you down. I am glad that you discovered Fiverr and somehow it revived your confidence. I am quoting some lines from the movie “Pursuit of Happiness”
"Don’t ever let somebody tell you… You can’t do something. Not even me. All right?
You got a dream… You gotta protect it. People can’t do somethin’ themselves, they wanna tell you you can’t do it. If you want somethin’, go get it. Period. "
Good for you! Keep working hard.
