I don't want to live anymore.
Why do you feel your life isn't worth living?
My life is so boring. It feels like I'm just existing.
Saying that has me really worried about you. You should really seek some help if that's really what you feel before you do something you can't take back. I'll help you every step of the way if you want.
I'm fine. I just want attention and this is the best way to get my friends worried about me.
Are you really telling the truth? Suicidal thoughts and constant feelings of boredom are symptoms of depression, which you should seek medical assistance if you have them. You shouldn't use depression to get attention; just talk to your friends more.
