I really plugged myself in to SR when i wanted to quit - it really helped - and I stayed - even when the voice in my head said I'd be ok to leave.
It's great you want to help your roommate, but I've seen many well meaning members trying to save someone else and both end up metaphorically drowning.
Point them in the direction of help by all means, but remember your own journey in all of this too.
Congrats on 6 days
