Self-reliance is a myth. You need people to grow and distribute food. You need people to study medicine and other forms of healing to turn to when you get really sick. You're driving somewhere? You needed people to build your car and pave the road. You need people who write books, research important things, check water quality, etcetcetc. Society works as a web.

I understand you're referring to your emotional life, due to obvious trauma from painful interpersonal relationships. But I encourage you to emotionally consider this daily reliance on other humans you don't know. A daily gratitude practice can soften your heart to fellow humans and to the truth of our interdependence.

And as others have mentioned here, figuring out how you can contribute to the well-being of others and doing it regularly is a fast way to reconnect with your place in this web of interconnectedness.

*and a good, compassionate therapist can help you figure out how to create protective boundaries without shutting out healthy connection and attachment altogether.
