Why did the administration post a message over the top of my pm to a friend of mine. For help with suicidal thoughts.?

I'm not suicidal. Saying if I am thinking about hurting myself or if my friend is click on this here (they had a place to click on that would lead u to a help center. In your country. And I clicked just out of curiosity and they said we at similar Worlds love you and a lot of people do.tell someone. Write down what I'm feeling. And it had pictures of teddy bears and sunshine and other supposedly. Happy signs. I was just telling my friend some things just ranting really. And all of a sudden I get a square box above my messages. Saying the above. I'm not going to harm myself myself. Nothing is private on here. Pms or anything else. And I already know that. But this was the first time they did that. Why they thought that idk. I was just telling him how I felt.
