I feel like it's really challenging for me to grasp what's going on here, but I think you might feel better if you separate yourself from this scene for a while. There are lots of fun things you can do that will probably be much more enjoyable, and better for your mental health. Talking to your friends in real life about this situation will definitely be more productive. If you had a falling out with this group, then it seems like it might be better to cut ties instead of fighting. Bringing more people into it will only prolong the fight and make it worse.
