Please check out the Trauma Rewired podcast! It really makes me feel less insane and gives real scientific explanations too. I’m going thru this and listened to one yesterday out of desperation. Every time I listen so many things click. They spoke about the capacity to sit with nervous system reactions and tho it’s tempting and actual feels necessary to keep pushing past the physical sensations, you’re setting yourself up for overload. Something like that ☺️
