Please don't kill yourself
A little online fight is nothing, you can get past this. I just went on your page and now I'm super worried. You are an awesome artist and we all say things we regret. I said something super mean to a friend and we didn't talk all that summer. If someone online is getting you down, just ignore or block them. This isn't something to kill yourself over, especially if you are depressed because someone who obviously does not know how to speak English (*cough cough* person below *cough cough*) is being rude or something. If it's a fight, it's a fight. Don't get weak, grow and get stronger.
Anyway, again, please don't kill yourself. I bet you are an amazing person and a little "bullying" is nothing. I got bullied, I didn't care and look at me now! Bullying is all based off of if you care or not.
I hope I helped
