Delete or no?

So this might seem petty to some people lol but I just feel like for New Years, I wanna delete people off my social media that I am no longer friends with or who bring me negativity. Is that wrong? I had a best friend of two years stab me in the back by betraying my trust and personally I just don’t feel she needs to be there anymore. Maybe I’m wrong but I just felt like this year has been a lot of negativity and I don’t want that next year. I’ll be moving away from a lot of it thankfully next year so I don’t wanna bring it along with bad memories. Has anyone decided to just cut ties with people to better their life and own health lol
