<human>: Okay, so I've never really posted anything like this before and this could all end up as ramblings but here goes.  

So, I'm currently 18 and have just started university this year and just like everybody else who leaves highschool I kind of drifted away from a lot of my friends. One of these friends happened to be my best friend of 6 years who I do still keep in contact with but have sort of distanced myself from because of the people he's started hanging around with. 
Anyway, he'd never done drugs before this year but started going clubbing with some of his new friends and he got heavily involved in drugs through them. He's told me that he'd go out and pop pills or do coke almost every weekend. I sat down and talked to him and told him that if he wasn't going to stop, to at least be safe about it. He promised me he was, however this weekend I got a call from someone he was with telling me that he'd OD-ed and had almost died and was currently in hospital.

He was released today after spending 3 or 4 nights in hospital, and a friend of mine told me that he'd had 3 or 4 drugs in his system.  However as happy as I am that he's still here with us,  I'm also super angry at him. I'm angry and upset and worried about his well being. I still haven't spoken to him since it happened and I'm fairly sure he doesn't know that I know what has happened. I just really don't know what to say to him and whether my feelings of anger towards him are even normal? Right now I feel as if I want to cut all ties, but at the same time I feel somewhat responsible for not getting through to him and stopping him from doing all these drugs in the first place.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: My best friend OD-ed on the weekend and I feel guilty for being angry at him and don't know how to approach the situation and talk to him about it.
