Hi @Former-Member,
It sounds like creating a safety plan is a good idea and it can be daunting to know where to start and is often something you would do following a long session as such you've just had, asI've read in other threads across the forum.
@Former-Member mentioned the beyond now app, which you can certainly mention here
This is a really goo starting place as it guides you through it the whole way and you will have a comprehensive plan at the end of all the prompts. If you are feeling triggered by putting this plan together, or need some support while doing this, you can contact the Suicide Call Back Service for support.

I hope doing the app is helpful for you
