I'm not sure any of us are qualified to advise on this. Assuming you have spoken to 'professionals', what did they advise and, why doesn't it seem to help?
From a laypersons point of view- I'd say- identifying your triggers would be an initial step. What is it that triggers such hate and extreme anger towards people? Can you avoid those triggers? If you hate hearing about peadophiles say- you mentioned Epstein in another thread- can you avoid the news or, avoid looking for reports on people like this? Can you figure out what makes you calm and what makes you angry and try and steer away from your triggers?
Sometimes I think we have to try and avoid feeding our obsessions. I tend to suffer with limerence I believe- obsessive crushes on guys. So- the reverse really. Fairytale love rather than hate. But, it still screws me up. I have to be really strict with myself that- when I do start thinking about a person- I make myself stop.
Are you ok on your own? Is there anyway you can work from home if just being around people triggers you? I try to avoid all people now where I can. Not because I want to kill them. Simply that I don't like being around them!
I suppose ultimately though- if this could become a reality- could you create a safety plan? So that you contact someone if you feel like you may actually act on your thoughts.
I imagine you must have a great deal of pent up anger to be feeling this. Do you exercise regularly? That could help to release some of the tension.
