Social Media Anxiety/OCD

Hey guys! I will try to make this as short as possible. So more recently, my obsessions and ocd thoughts have been circling around social media, or anything that is virtual, texting,calling etc. Anyway, I seem to get anxiety from things like blocking people. I'll give an example, I had some terrible toxic coworkers at a previous job i recently quit, after a lot of toxic fights and messages, I ended up blocking one of them, because I woke up one morning to a bunch of horrible texts, and ended up ruining my mood for the day. For some reason, when i block people, i get thoughts like, why did you do it?You did it cuz you're scared, you're afraid of them or whatever. Anyway i also get intrusive images, usually of people i had a bad experience with. I did unblock the person before, but ended up blocking him again because i wanted to make sure that I could live my life in peace even if this person was on my blocked list. I start thinking that blocking someone is a constant reminder that you dislike or hate that person, and feel like if i dont unblock them then they will haunt me forever with intrusive images. I know this is OCD, ive experienced this many times before with diff people or experiences, but I am truly tired of it, I would like someone to give me insight, maybe something i could try or practice. Sometimes I smoke weed to relax and ease my mind, sometimes it works, other times it can almost have adverse affects. Anyway, Im thinking it really doesnt matter if the person is blocked or unblocked in the sense that either way OCD will try to bother me. Can anyone help with this? Thank you.
