@Grigor I totally get what you mean ...
I too haven't been in a grocery store, pharmacy or any other type of store in many, many months ...
I can't drive anymore, my world has been shrinking at an exponential rate.
I stay mentally sane only b/c I've a very curious mind, a loving and supporting family and an ME doctor who is trying his best to help.
Apart from ballet dancing, which was your profession, you must be missing every possible human activity that we PWME cannot do anymore.
Being ill with ME is an everyday lesson and struggle with keeping your spirit high while adapting to a ridiculously low level of activity and terrible low quality of life.
I'm looking forward to the day when we'll have access to Centers of Excellence for real treatments and also to a non ballet dancing party
