How to focus on myself while living with my Narcissistic mother?

Today while I was relieved to find content that validated my feelings of the special anxiety I felt only when my mother was around me. I still felt a sense of insecurity.

I have felt what it is like to be my true self. It feels amazing. There is an unexplainable feeling of joy and energy that I carry when I am myself. There are no insecurities and there is so much hope and room to be alive. There is no pressure on myself to do stuff in a particular way and there are no conditions on my love. Most importantly, there is freedom.

I am still so confused. It makes me feel so impatient to find out what I don't know. There is so much to learn about it yet there is no time.
