My mom knows I have a history of suicidal ideation. She doesn't like the fact that I have those thoughts, though there's not much she can do. She's convinced herself I won't try anything, at least, so it's not like I'm not suicide watch. My father knew, too, as I voluntarily admitted myself when I was 16 due to constant breakdowns; same deal with him, too, as the professionals told both of them that suicidal thoughts were "normal".
