What if I don’t have any best friends and I don’t care enough about my other friends because they don’t care about me? The only friends I have are my friends because they want a human to talk to, not because of my personality. Whenever I talk about my troubles they change the topic. Whenever I want help they make an excuse. Whenever I try to have a constructive debate they start yelling and walk away. Just because you won’t do this for your friend doesn’t men you’re a fake friend. There are many types of fake friends, depending on the victim. I could be a fake friend. You could be a fake friend. Anyone could be. I do believe in toxic people, but even those aren’t “bad”. I am toxic to some people because they’re just too different. You can have a toxic friend who really cares about you, but just isn’t very good for your mental health. Toxic doesn’t equal mean, and fake friends aren’t pure evil. No one is. Like I said to my toxic friend, there is not good or evil, we’re all just people.

Also stop calling people toxic if they’re not just to make them shut up, those words can haunt them for weeks maybe even years like it did to me.
