friend problems

so, my friend for quite a long time now does this thing where she texts me and all my friends implying that she’s going to kill herself, i understand if she’s upset and i do try to help her but than she never does and it puts me in a bad mood as i get worried and today she did it for the 4th time on valentine’s day when i’m trying to have a nice evening with my boyfriend and it really made me mad, what should i do??? should i talk to her???
