Hops on soapbox:
No one needs you. They prefer your presence in their life. Self-preservation of life is the first law of nature. Despite how much we may think we need someone, we learn to live without them if we have to.
Thus, what this need we feel is, is a selfless love to share part of our life with one another. Therefore overwhelming gratitude to my family and friends who prefer sharing part of their life with me. Thank you for not needing me, yet still choosing my presence. Infinite Love
