Oh gosh, so many scary parts of the terrible, depressing road of addiction.
Probably the scariest times for me came while I was lying in bed at night, trying to sleep, and I would obsess over and over, awfulizing, feeling full of dread, wondering where they were, if they were on the street, or lying dead somewhere of an OD.....
and then realizing there was nothing I could do to fix it.
Not pleasant memories
