and mind the razor blades taped under the handrails on the stairs most likely have AIDS infected blood on them!!
Jfc why would anyone want to give you aids??? Fucking hell. But yeah, addicts don't care about anything in life besides the next hit. If you're in that position, it's unlikely you'll change your opinions about yourself. It's more than just likely that you'll die in your self destructive ways to the escapism.
No one can help them because it's a deeply personal and internalised issue. Some sort of trauma or self worth issues. People can talk to you, take care of you, but it won't just go away by itself. One has to face the issues and work through them, which is not pleasant as you'll have to admit a lot of very, very uncomfortable things to yourself.
Most addicts therefore just tune off and do whatever it takes to get their high. It's the only time when they feel good and forget about their problems. The downs are ignored, and only the ups are chased. And what happens during the downs can be drowned out by the ups.
They are very aware of what they're doing to themselves but it's self determined damnation. They feel like they deserve it, too, at some point. And then they're just saying

whatever.
The girl in the interview was quite alright looking, so I guess they sifted through a whole street of low end prostitutes to find someone presentable. I didn't realise when I opened the thread that it's one of those kind of streets... But as soon as it was pointed out, it made immediate sense.
