I am so so sorry for your loss, words can not describe how awful I feel for you and your friend
my moms best friend had shot herself, not long after my mom talked to her... whats worse is she talked to my mom about "if people who had committed suicide went to heaven" as if for another person but really was asking for herself.... my mom felt so guilty so I know that your friend really, really needs you right now..

Again so, so sorry, best of wishes, and ill keep you both in my thoughts
