This is probably one of the things i find the hardest to manage. Fatigue is awful. You feel completely drained and unable to muster the energy to fight. I find being honest and loving with yourself. Be true and know that although you might get the occasional good day, that doesnt mean you have to over do it. Know your limits and accept that as a part of your recovery process you need to sleep and rest - which is easier said than done. If you have kids, accept that you are completely justified in sleeping on the couch while they destroy the house! think of it as a 80% 20% balance.
