Stop going back and forth with people. Stop wasting your precious energy on people, conversations, arguments, and exchanges that aren’t worth it. What you choose to focus on amplifies, so if you choose to engage with the miserable and mentally unstable, you will bring misery and instability into your life. Use your energy to foster all things that are good, that make you feel more energized, conversations that you can learn and growth from instead, and if/when someone tries to get you out of character simply remove yourself from that situation, no explanations needed. Protect your energy, don’t allow others access to you so easily.
