I don't know what to say except...
Stop being a drama queen!!!
If you feel bad, then I'm very sorry to hear that. You want to talk crap about being suicidal? Do NOT do it here!
And if you think I"m being mean and cruel, guess what? It's a mean and cruel world and yes, I know what I'm talking about since I've been down that road in my life.
Focus on being yourself and don't take all critisism to heart because it'll eat you alive. You can do everything right and there will always be those who'll find things wrong.
In the immortal words of Kinomoto Sakura: "Zettai Daijoubu Daioh(Everything will definitely be alright)"
Whether you take my advice or not, it's your decision.
