I want to challenge your thinking on this.
Respectfully, your mother didn't tell you to kill yourself.
The first part, "you're not my child," is shitty because it's a rejection. It's also saying, "You're not me." Well, good! She had an autonomous child, not a clone. Some people are sorely disappointed when their children aren't just like them, and that's their own problem if they can't accept it. It's not the child's fault, thought they have the power to make the child suffer for their problem for a long time. You're an adult now, you're not a child. The problem can go back to her.
The second part is what I'm specifically challenging, though:
"why didn't you killed yourself years ago, you don't have enough courage to do it, all you can do is complain"
Some people think that if someone else keeps going on about suicide, they're using it as leverage, as emotional blackmail. I'm not at all saying she's right, but it may be that she expects if your problems were real, that you would do something about them, either kill yourself or find a way to solve them. And that may be something she sees in herself, that she wouldn't complain, she'd either kill herself or fix herself, and therefore rejects you as having come from her if you don't do the same. I'm not at all saying it's logical, or that she even walks that talk, but recognizing that this may be her logic. It is, however, not a command that you kill yourself.
But it's a little bit scary, I am sorry for my friends, and I don't know if I should deactivate all my social pages, I don't know how to write letter that no one will blame anyone in my death
If you're hearing your mother as commanding you to "Kill yourself," whoa. Number one, who made her the boss of whether you exist or not as an adult, whether you live or die? Who gave her the power that you have to do what she says, something extreme that you're afraid of? It's
your life or death, and either you own it or she does. If she does, then hand her your method and demand she kill you. If you can't own it, then no one does, it does not default to her or you would already be exactly what she wants and doing exactly what she wants.
I know I spoke very bluntly here. It doesn't mean I don't have compassion for your suffering and experiences. What it means is that I see you functioning in an illusion, like a dream, and I'm saying, "Wake up!" You may not value my perspective or my approach, that's cool, I respect that. I sincerely mean you no harm. I don't negate you, only what you're interpreting and the power you're giving your mother that she has no right to, and wouldn't know what to do with if she had it anyway.
