Belonging – Remembering Ourselves Home, a book by Toko-pa Turner | Toko-pa's Official Website

I haven't finished it yet, but it explores our deep yearning to belong and how this is a part of the human condition. She speaks about belonging as something ancient and something which is more than having friends or volunteering, etc. It's a strangely reassuring and sad book. It looks at how we can belong and how we ostracize *ourselves*, as well as how we are cast out from the places where we should belong - family, community, etc.

So yes, I get the search for belonging. I think it's why I gravitate back to therapy even when I find my therapist painful. I yearn to belong and yet I am also fearful of it: the fake relationship with her is as much as I can manage. I push away from all of my personal relationships and whilst I still do this with her, I have to worry about it less.
