I had become pretty much bed ridden from a combination of stress that was way too heavy, trying to wear masks to suit everyone else, from consuming things that were continually working against me (although they're marketed and taught as being very necessary), and living several decades with trying to suppress my feelings that I thought would bring discomfort to others instead of processing them.
Once I was able to let the stressful job scene go, change my living environment (like drastically), change my consumption habits (also drastically), fond help in places I didn't even know I needed to be looking in, and received quality talk therapy from a local sexual/domestic abuse shelter, I slept for about a month straight. Part of it was relief in knowing I was finally in more capable hands of actual healing, and part of it was sheer exhaustion of trying to survive in the only ways I'd been taught up until that point.
Re-learning how to fuel and surround myself in the most basic of ways with the cleanest most whole foods/beverages/products possible, as well as re-learning how to breathe, move, and talk to myself were some of my greatest saving graces. I responded in much more detail in your other thread. It's been a long, strange, uncomfortable, yet very eye-opening trip in my world, that's for sure.
