DON'T GIVE UP ON THE DREAM! :')
I don't see any reason for why you should feel ashamed or be bullied for those videos >:O
What I think you should do is actually share them around, because I'm sure there's a much higher percentage of people out there who won't bully you. And once your videos start getting more popular and gaining positive attention the bullies will just look dumb(er) than they already do^o^
every YouTuber gets bullied, but not because the bullies genuinely hate the fact that they're making videos, it's becaue they hate the fact that they're usually doing better than they are at life at the same time

Good luck
