Four Pelvic Tilts and Back to Bed!

Well, this is a very sorry state of affairs. I am only able to manage four pelvic tilts before the muscles completely fatigue. I have trigger point pain in numerous sites in my upper body. I have no "fuel" and need to go food shopping - but have no energy to even get about my flat let alone manage that. I can't bear this - however, I just don't think I can fight this one. I need to rest and wait until I have energy again - however long that might take.
