still tired

I think your name probably says a lot about this. Fatigue is a huge drain on mental power as well as physical power. Your body has been through a lot and you are readjusting to it all and probably still healing on some level that is below the level of “seeing the iceberg”. A lot of people think that GBS and CIDP are “only” peripheral, but there is a lot of others that believe that many people with these illnesses have some central effects. The central effects must also be healed.
FYI, pain is also a huge drain and having to re”make” your way of processing in the world is hard for adults.
