I am new to MG, so I am still trying to figure out my own dang body. Is it normal to have days where you feel like you could run a marathon and others when it is hard to just walk up a flight of stairs? The other day I felt defeated and could barely lift my arms to do my hair (Mestonin helped, but not as well as usual that day) and now today I only feel "typical" weakness (which for me is in my neck and legs and sometimes my arms). I am formerly very athletic (used to run 40 miles a week, triathlons, etc.) and am very driven which is my biggest weakness because relaxing is not something I do well. All I could do was force myself to rest and cry because I am not used to my body "not working" right. Is this now my new normal?
