Does anyone else hate stalk others?

To sum up a long story I have been for a lack of better terms compulsively checking the social media pages of someone I hate just to make sure they aren’t posting about me. I feel like it stems from this life long struggle of not being able to handle others talking about me behind my back, esp lying about things I’ve said/done, and I don’t know if that pertains directly to autism or not. Kinda wanting to know if others with autism also encounter this problem of not being able to let things go and ruminating in the past. I know I should just not gaf about what others think or say but it’s like an itch that must be scratched and as soon as I’ve seen that they haven’t posted anything the itch goes away but it always comes back. I’ve tried to not look and ignore it but I can’t get it off my mind and I’m left asking myself what if they are posting about me and saying horrible things like before and I break and look and the cycle starts anew. I just find myself to be overly paranoid after something happens that I tend to go over the top in trying to protect myself from it happening again and I have no way of stopping it so atleast if I know what’s being said about me it seems to quell the anxiety and fear that comes. Ok rant over thank you to anyone who stayed this long
