Pure1rish Hello, I will try to tell you about the method of Nais SOUBIROU, I talked to other post as this will really helped me get better. This is to understand that we have two brains: the brain of reason and the emotional brain (solar plexus). The solar plexus produces emotions but can not express and when they are bad (such as anger for example), they accumulate within us and make us sick. We must therefore establish a dialogue between the brain of reason (head) and the solar plexus to defuse negative feelings that affect us. You can find this reading here: http://www.amazon.fr/Se-d%C3%A9livrer-Boule-Au-Ventre-ebook/dp/B01BKIW9RM/ref=sr_1_1?ie=UTF8&qid=1456222122&sr=8-1&keywords=nais+soubirou (it's not very long so you can translate with odinateur). So you really have reason to accept your fatigue and especially as you did the analyzes and they are good do not worry. Do not attempt to explain this state of exhaustion underlying disease because otherwise you risk creating negative emotions suplémentaires and be even more tired. (I made this mistake at first because I thought I had necessarily to be a hidden disease as tired!). I also wish to highlight the importance of daylight for his action is vital to our brain and to the secretion of dopamine. Good recovery to you, patience, and I'm sure you'll come out of this state because you already understand many things and have the will.
