An old friend, who I stopped being friends with over a year ago as they were bullying me, posted a public social media post which whilst it did not name me, it is clearly about me. The post was very detailed, contained false information on the entire situation (massive pitty post) and mentioned some serious issues that this 'false situation' caused them to be/feel. I should note it's accessible by my employer too. I'm not sure if I'm sensitive to it all because it made me feel like it was a personal attack on me, but I feel violated. Not only this but I have received other attacks in the past, publically, on social media by their mum and sister as they have lied to them about the reasons why we are no longer friends. There are other things directly from the ex-friend that have happened in the past but I won't go into those.
Am I overreacting or is this a form of harassment? I feel like I am constantly looking over my shoulder. Everyone related to this person is blocked on my social media/phone numbers but I can't help but worry what's next. I have been ignoring everything and moving on and just when I've forgotten about it all, it feels like there is something new. It's also hard to ignore when things are being made public for mutual friends to see. It's all very high school drama by older women and I'd just like to be left alone.
