Could be alexithymia you're experiencing @creative_writer!
As for asking for needs to be met - I reckon it's a practice thing. It was soooo difficult and uncomfortable for me when I first started trying to vocalise my needs or my boundaries. Got easier over time.
Chronic pain is definitely a whole nother layer of complexity, and I imagine it's one that few would understand. Like, the ultimate sensory overwhelm, where your pain receptors are screaming louder than the bright lights or noisy environment.
Hmmm... I wonder if that is part of it too? As in, we can't separate our minds from our bodies, and we feel our emotions in our bodies. If you have chronic pain, it's likely that your brain might withdraw or try to block the pain, thus also withdrawing from the emotional feelings parts of your body. This is all based on my own random assortment of mental health knowledge mind you so take it with a grain of salt, but just something that popped into my head I thought I'd share.
