I want to send hate messages to suicidal people
That is shocking. Do you know how serious suicide is?
Yes, I've been there once, but I hate seeing junkies talking about their "suicidal thoughts"
Suicide is really not the answer, but this is no way to prevent it. Stop the nastiness and make sure these people get help properly instead of being emotionally abused. You know how it feels to be depressed, it is the last thing you would ever want for them to feel even worse.
I'll talk about it with them but I'll keep sending hate messages.
No, you should really stop sending the hate. That is not what these people need right now. How about sending messages of kindness and encouragement, don't you think it's better to see them happy?
