If you feel the friendships you have are worth saving, you can try to talk to the group about it. Talk to the people you’re closest to in the group – if they also feel the behaviour is toxic, you can try to talk to the others.
Use “I” statements when you’re raising the issues with the group, like, “I feel we can be more supportive of each other. I think it would be great if we were kinder to each other…”
Remember that the entire group will need to want to change and they may get defensive or become even more toxic when you raise your concerns.
If they do, it might be time to look for healthier friendships that make you happy.
