It is possible that they have since grown up and realized that their actions at the time were cruel. That said, that obviously doesn’t erase the lasting damage they did to your mental health, and I do not blame you at all for being upset over seeing this. The best option here may just be to block them and see about getting back into therapy.

Send them a private message addressing the bullying. My guess is a few of them have seen the error of their ways and will apologize and a few will deny it ever happened. Block the dipshits. Shit, block them all if you want.

Maybe you were the bully?

I have zero clue how any of my former bullies are doing. Know why? Because I never bother to look them up because I don’t care enough about them to look them up. They could have grown up and changed, or they could still be the narcissistic twats I knew, but I don’t care to know. One of them tried contacting me on social media, and I ignored the request.

You have to tell anti depressants every day, that’s how they work.

Oooh, I hope you commented on their page or a post saying it's nice they're anti-bullying, but you wish they felt the same way when they bullied you almost to suicide when you were in college.
