Are toxic people worth it?

I have had the wonderful pleasure, as many people have, of having and keeping toxic people in my life. Now you would think, they're toxic why keep them? Normally I would agree with you. I am a big believer of cutting off people that aren't good for you, mentally, emotionally and especially physically. Something I've been struggling with though is what's considered too toxic? No one is perfectly, I certainly am not. I have done and do plenty of toxic things. We're all human and sometimes I think we are cruel and self-centered by nature. But at what point is someone too toxic to keep in your life?

I used to be very black and white when it came to choices, friendships, etc. I have been in therapy for a little while, and this has been something I have been working on. I don't think everything should always be so black and white. But I have been struggling to to decide when I want to cut someone off if this is still just me being too black and white or if its really time to let someone go.

I have never had many friends so being alone wasn't really scary. But I have allowed many people into my life that do shitty things because I was tired of being alone. I'm getting to the point in my life where I am trying to find real genuine friends. While I still think it's important to do things alone, I've realized how lonely I am in life. But I don't think this is an excuse to let people treat me poorly. I also don't know if I can recognize a good friend. Recently I've been stood up, pushed aside, forgotten, replaced and lied to. I kept these people around because I'm almost 30 and didn't want to lose anymore friends. But maybe it's time for a life refresh and a new chapter.
