Dear one, I can't help but think that you should listen to your body and yourself. If you dread SFQ, maybe you should take a little break. Maybe it's not for you. If your pain is worse when doing the exercises, perhaps you should try doing only the ones that don't cause pain, or the one you can do lying down, if that's comfortable for you. There might be another form of energy work that suits you perfectly, or perhaps something that is not so much about energy. I feel you should be proud of yourself for persisting as long as you have and maintaining enough faith and discipline to practice the exercises and meditations while experiencing no improvement. Mayber it's time to let others do some of the work for you through their prayers or by having someone else work on you. My heart goes out to you.
