Day 1: scared but hopeful

I just did week 1, Day 1 of the SEP. i stumbled upon this thread after reading Sarno’s in desperation overnight.
To back up, I’ve been struggling with lower back pain that is closer to my buttocks and side thighs for over 2 months now. What started as a mild twinge grew very quickly into agonizing pain and bed rest. I got better then did some activity and worse again, better, more activity and worse again. And then So bad that I was rushed to ER. Got prescription strength meds, toradol shots and steroid trigger shot in the muscle. What’s interesting is that I never truly had an accident or reason for injury that was bad enough to put me into this level of MISERY.
Honestly NOTHING TRULY HELPS. HIGH dose painkillers mask the pain for some time. Steroid was nice for literally three days and then I was back to square one. CT and Xrays show L5-S1 DDD, and the spine doc thinks there might be a bulge but is waiting on MRI. While I wait for my insurance to get cracking on approving my MRI, I’m lying down helpless. I haven’t mustered the courage to start PT. So after bawling my lungs out in desperation last night I saw some redditer say “Sarno saved my life.” So I went on a googling spree, saw “all the rage” documentary, bought his book and literally couldn’t put it down. It felt like the book was made for ME. It spoke to ME and seemed to be about me too. I felt a glimmer of hope. I laughed and giggled like a school girl. But I also cried … big time
So, here I am. Honestly, in terms of being sold on the theory, I think I’ve 90% accepted it. What my biggest issue is getting up from bed and feeling pain. That makes me disappointed that Its not working. I’m also scared AF to do anything but walk back and forth from the bathroom to bed. Because any pain I feel, feels like a set back. So, flood me with some positivity and if others feel this too?
Wishing everyone a pain free existence! Such a blessing
