Setting healthy boundaries is crucial for our well-being, especially with difficult people. Boundaries define what's okay and not okay for us emotionally, physically, and mentally. Reflect on your needs and communicate them clearly but kindly. Stick to your boundaries consistently to show they're important. Take care of yourself and seek support from understanding people. Saying no is okay, and it's not about rejecting others but prioritizing yourself. Boundaries are self-care, helping us build positive relationships and live happier lives.
