I lost a close friend just this way. It broke my heart being unable to help him. It was over 30 years ago that he died, and I still remember him with sorrow and regret. I don’t feel like sharing the stories; just wanted to say that I understand the anguish you feel. And also your friend’s anguish. Don’t be angry with your friend. It won’t help, and will only sour your memories of a loved one. I’m really sorry for you.
I’m not going to be angry. I’m just going to take it as it is because there’s nothing else I can do.
