I don't think it's right to call suicidal people "Angels", they are not angels, they are sick. Calling them angels is pushing a positive narrative on the idea of suicide, like it's some kind of teenage romance movie, in contrast to the idea of your post. The problem I have with these kinds of posts is that they unknowingly Romanticize the notion of death.
There's a clear line between emotional and clinical depression. I'm not doubting your credibility, i would just like to point out to some people and to you that it may not be clinically depressed. Maybe all of you are just is salty that your mommy yelled at you, that your crush doesn't look your way cause he thinks your fat, or that your friends talk behind your back because they themselves are insecure about themselves.
I myself have been on some tough spots; before, everytime I laugh or even had a hint of fun with my friends a lingering voice in my head tells me how none of it matters since we're all just gonna graduate and forget about each other, and that nothing I or anyone does matters since we're all gonna die on the long run. I used to have anxiety attacks at night when I think about the future, bad enough to make me wanna cry and punch a wall. I would even have these real thoughts of stabbing myself with a big ass knife as I wash the dishes (not the self destructive thoughts like "I wonder what would happen if i stabbed myself" but thoughts like "Should I stab myself right here and now or not"). Then one day I just thought fuck it, just because it doesn't matter doesn't mean i should ruin myself with these thoughts. I'll die one day but I started not caring.
I'm not hating on you for speaking out or anything, I just hate the idea of people jumping straight to "I'm suicidal" without having to experience the real hardships of depression like some people seriously have. I hate it since I once thought Suicidal people are "Angels" too, I liked the idea of calling myself an angel but that was just a way to make me feel special during my predicament. Depression is a serious mental condition and it isn't right to brand it as some kind of positively romanticized movie. Don't think of them as Angels cause they're not.
