Books on trauma, grief, and feeling alone?

Hey there,

To keep it short, I recently lost my father. We had not spoken for years prior to his diagnosis, due to a lot of trauma. We reconnected, and he seemed sincerely remorseful about the damage he'd done. He felt his illness was his karma – while I dont necessarily agree, it showed me his apologies were genuine.

It healed some things in me, and made me realise how detrimental my PTSD has been, but also left me feeling very broken.

I'm also deeply hurt by some who are close to me who were hurtful during this time and made me feel very alone.

I have no idea if such a book exists, but I'd really like a workbook or self help title that can cover any, or all, of this – the trauma, the grief, and dealing with lack of empathy from those I expected it most from. It feels .. isolating.

I found one book I thought might be good, "forgiving what you can't forget", but from the reviews it seems more religious than I'd like .. I've bounced around from pagan to beginner Buddhist to agnostic and several things in between, so I don't know if something overly religious would be comforting to me. I am open to some light spiritual stuff and occasional religious blurb, though.

I hope all that makes sense. I'm going to be trying to journal again and want something to sorta guide it. I know I should also seek counseling at some point, but need something like this in the meantime.

Thank you so much in advance. ♡
