Secondly. I doubt any agency is going to hurt or drug you over that. Investigate you? Maybe. But its not worth the money.
Just keep in mind all the dangerous people who these groups investigated that they did nothing about that went on to do bad stuff. Although I'm sure these groups do take threats seriously, I don't think you are a threat.
I'm worried about your mental health is all. I'm not saying that in a way like "you sound suicidal" because you don't at all. You just sound paranoid. Wishing you the best brother
