This is a very good mental health hotline for email conversations.
I've used this when I was really down and out.

Not sharing this because someone just killed themselves or anything...I just think we shouldn't have to wait until that happens to share things like this.
If anyone ever needs someone to chat to...I don't get notifications on this app for some reason, but I WILL respond with care when I do see.
