I've been through some very similar stuff. It was two years after "I" was blown to pieces before I had really integrated these strong pangs of anxiety, memories that I was nothing at all and that ultimately reality is terrifyingly absurd. It's been a long process of learning that these pangs are important learning experiences, that they are fuel for compassion for others, that curiosity and awareness transform them into something else... etc. etc. down the rabbithole of self-care for the unwilling mystic.

If you're interested in what I did with all that since then, I'd be happy to chat more and share what I've learned, where I'm at, and where I'm headed. Seconded on the cup of virtual coffee, /u/artsyca, although of course I'm perfectly happy not to crash y'all's party.
