NC due to this situation maybe outing where I live! Not sure here to start with this one, but my friend has become obsessive and I'm not sure if there's anything I can do.
To cut a long story short, the local council did some work to improve facilities near to where I live. The work was very good and welcomed by most people who live nearby. My friend lives further away than I do to where most of the work was done but comes to the area regularly. Despite the majority of people being really happy with what was done, my friend was upset about one aspect of it. She tried to whip locals into a frenzy and started a petition demanding the council change their minds. She got what she wanted but it had an unintended consequence that something else they were planning had to be scrapped. My friend went on to complain repeatedly to the council about it but they didn't change their minds. At this point she tried to backtrack as a few people started to blame her for what had happened, but nothing changed.
Since this happened, my friend has not been able to let it go. She has started a campaign against the council which has involved sending hundreds of emails over the past month. She seems to believe she's performing some kind of public service by making complaints about every little thing she can think of but it's become obsessive and she is being vindictive. She is of the opinion that council workers are lazy and overpaid and at least they are doing some work for her council tax money. Yes, she did actually say that.
If you were me, would you try talking to her about possibly letting go of this now? I am worried about how much time she has dedicated to this, it has sometimes involved her staying up until the early hours writing complaints.
