Really sorry to hear that, as has been said, be with people and talk, not for your friend as he is at peace now, but for you.
I had a workmate take his own life 20 years ago, I dropped him off at home laughing and joking, said see you in the morning, he laughed and replied dont be late....
I never saw him alive again
Got home and my cousin who I was living with was really late home and annoyed as "some selfish ba$tard" in his words had chucked themselves in front of a train
Was on time(for once) the next morning as I pulled up outside Lee`s house...... Beeped the horn, nothing, waited, beeped again and his dad came out, said Lee wouldnt be in and who did he need to talk to at work.
I found out from work later that day, that Lee had stepped in front of a train the night before...... the same train my cousin had been on.
It destroyed his family, his mum never got over it, but he had planned it for quite a while, he`d been down there with someone else and mentioned in passing that this would be a good place to top yourself if you ever wanted too. Chris never thought anything of it at the time but beat himself up about it for ages afterwards, could he have done anything ? should he have picked up on that comment ? etc
Lee sadly didnt want to be around anymore, he kept everyone out of his decision to take his own life, but the fallout with those left behind was huge......
So very sad for your loss
