Many of us get depressed; I for one was once depressed due to one relationship with someone with a few bad experiences that made them want to commit suicide.
I stopped her from doing so around 15 times, most of those times I suddenly got a really bad feeling like when I was at a football game (I was a percussionist who was fond of playing xylophones and sometimes the cymbals in band)
Had my phone with my clothes and asked a friend if I could use his phone that he never let go of and texted her and got her not to do it. Getting her psychiatric help and helping her eventually piled up and took its toll on me emotionally.
