I do always forget how I'm from a much more bougie area than most people, I've literally never seen someone on meth before let alone been offered it. I can understand then, especially for a police force in the area, that they have some sort of experience with not outright murdering people on drugs. I just think it's easy to fall into the moral trap of "I should have done something" when in hindsight, and I don't think it's very productive to dwell too much on past actions like this - each action has to be taken with the present considerations in mind, so I don't want you to blame yourself for what happened to this woman (especially because you aren't 100% sure what happened to her).

I'm just trying to be supportive, I guess, and I don't want you to lay so much responsibility on yourself. I can literally never imagine myself being a methhead, so putting myself in this story is difficult. I just hope you don't spend a ton of time worrying about what could have been.
