So I found out a few months ago that wanting to ‘not exist’ or wishing you could ‘just sleep forever’ is also considered suicidal (specifically suicidal idealization). It shocked me cause I used to think that way when I was younger but had previously thought that being suicidal meant explicitly wanting to die.. but it actually involves wanting to not live too.
I think its an important thing to note cause it might allow someone to realize the severity of their condition earlier.
