Re: ready to go...
If it's really what you feel like doing, I support you.
I agree that this fandom doesn't have the nicest of people in it, that can really hurt your feelings, or just be out-right mean.
Personally, I think your covers are amazing!
But yeah, I would suggest a break would be a great idea. And it's ok if you don't come back to utau. If you feel happiest without it, then that's great!
I just hope you're happy with your decision.
We will all miss you very much <3
