If you are a kind person you might worry you are kicking people out who need help? Maybe you feel you should be stronger and be able to help these people while still protecting yourself? Those are my reasons....plus I'm often confused if the problem lies with the person or with myself. I don't know your reasons but I am familiar with the problem and it sucks. Keep taking care of yourself and ridding yourself of people who no longer serve you in healthy ways. We support you. You are important and your feelings are valid.
