Yeeeep! This has been happening to me loads in the past few weeks. I haven't really been happy though, my mood has been up and down but especially anxious. I also don't plan on doing anything but the suicidal thoughts are just so intrusive and come out of no where

I did tell a mental health professional about it but she just told me the importance of staying alive, I think it was pretty clear that I wasn't in immediate danger from myself. In NZ they're pretty strict about how seriously they take suicidal ideation (meaning they don't really take it that serious); most of the time they will just get you into therapy. Heck, when I actually did attempt they didn't even keep me overnight in the hospital.
TW: violence, blood
I also keep having intrusive visual thoughts of me stabbing myself and blood being everywhere; I would never do that but yeah... It's quite distressing
