Hello, Pandapeach.

There is nothing wrong with feeling sad, sadness is a natural emotion. Don’t try to stop it, avoid it, press it. Meditate on it. You will understand the deeper unconscious ground of it. If you are hurt by someone’s unkind and unfair behavior, try to let it go. We all have our own reasons to act in a certain way and mostly we behave badly towards others because of our own weaknesses. Understand him, forgive him and let it go.

Accept your sadness in meditation, feel it fully, hug it, love it and it will leave like mist fog when the sun rises.

Be healthy and peaceful.
Namaste
