This is a judgment call and experience is the best teacher. Be gentle with yourself and others. We tend to judge ourselves by our intentions and others by their behavior. Forgiveness is critical to maintaining healthy relationships. Whatever happens, you can choose how to react.
Healthy communications is the result of effort and wise choices.
None of us is perfect. Everyone makes mistakes and we can all learn from experience. Then choose accordingly and know that each day can be a new beginning. You can start over at any time and find an alternative to the way you communicate - with yourself and others. Learn to forgive yourself and others for mistakes.
