Friend 1 - called me retarded for going on a walk and changing my diet (he tried to blackpill me it won't change my life anyways)
Friend 2 - sabotaged my career when I started becoming successful
Friend 3 - ignored meaningful conversations to send a bunch of dumb normie memes
Friend 4 - mind was rotten, all he did was send me porn and tiktoks how I should hate all women despite asking him not to
Friend 5 - turned out to be a pet abuser and saw no problem with it

This all happened throughout 2,5 years. Decided to cut these people off from my life since they brought mostly negative things to my life. Now I am all alone, with no one to share my thoughts with. I have no one to share my joy with, to mourn about our struggles. Without the internet, all I have left are trivial shallow conversations about weather or how did my exams go.
I thought I would be happier without them, but turns out it's pretty lonely not having someone to talk to for weeks. They were fake and I know I made the "right decision", but somehow I don't feel okay with it.

Can someone give me advice how to live with it, or maybe tell me how I'm wrong?
