Dear human, thank your for sharing and reaching out. I understand that you're going through a difficult time because you're unable to perceive happiness even when things are normal. This is quite common and all individuals might experience this at some point in their life. This might be due to past trauma, negative life incidents wherein you're unable to come out of it even when everything has became normal or this might be because of lack of purpose in life. The term "Happiness" instills different meaning for different people, and thus you'd have to search for your purpose and happiness. Therapy would help you to identify and unravel your thought patterns related to your unhappiness and would help you to become aware of why you're not finding happiness even when things are normal.

It could be due to various reasons.. When expectations aren't met.. When people are unable to understand you., etc.
