Most importantly, I am truly sorry for the anguish and pain of losing your friend. That must be very difficult for you, sorry.
As with SR, the fellowship of AA simply shares experience, strength and hope of what is was like - what happened and what it is like now. It is cruel and ignorant for someone in the fellowship to offer up nonsensical opinions regarding why a friend killed themselves. That's awful......
Please keep working your program as best as you can. That is all any of us can do.
Kind Regards
