friend relies on me for support
I have a friend who has recently been struggling with suicidal ideation and it is triggering for me.
I have let them into my house and stayed with them to make sure they don't do anything.
I think that their active ideation and overall stress I experience from these situations have triggered my own problems, and I had a sudden relapse after years of not having such thoughts.
They do get help from mental health specialists, but these specialists don't work as crisis hotlines obviously, and I do, I guess.
Because I obviously can't just abandon my friend in this situation. I am getting unreasonably angry that they don't even think about my feelings before texting me, though.
I could let them know that it is triggering for me, but then they will just kill themselves instead of texting me??? Doesn't seem like a good option.
I could just call an ambulance in the next such instance against their will, but it's obviously a one-time decision (won't be friends after that) and I'll be the one to ruin their life (at the very least, they won't be able to work in their field after such hospitalisation) with this one decision.
I can never know when it's actual serious intent and when it's not. They haven't had actual attempts as far as I know. So an ambulance can be a complete overreaction and it will break their trust in all people. But how can I just ignore the situation, thinking that it's nothing, if it turns out to be serious later? I always have to engage in triggering conversation and let them do anything they need for support (such as coming to my house).
What do I do? Asking for both advice and support here. :(
