I suggest viewing your circle of friends like a garden. Just as you must "deadhead" flowers to ensure energy goes to healthy blooms, you must sometimes distance yourself from "invasive" or toxic people who drain your resources. Consider the importance of setting boundaries to protect your bandwidth. This involves recognizing when a relationship has become consistently energy-draining, and having a direct, honest conversation with the person to address the issue.
Enforcing boundaries if there is no change in behavior is the responsibility of the Gardener: Being a "responsible steward" of your own energy ensures you remain available to help those who are genuinely in need. This process isn't an act of cruelty, but is necessary maintenance for personal growth and well-being.
