We grow old, but the child within us remains the same age. He is superior to hours, minutes and seconds. Nothing else in life is. A child inside you is more powerful than time.
I got interested in the concept of inner child when I started going to therapy. I have been diagnosed with depression 3 years ago. Since then I learned a lot about schema therapy, which refers mostly to our inner child and how this little traumatised human inside us affects our thoughts, behaviour and feelings. This form of therapy helped me a lot and there is a lot of literature on it online for free. I hope you share this with anyone who might need it or maybe that person is you.
I hope your inner child is feeling safe inside you.
