Thanks @Former-Member
I do understand what you are experiencing & feeling. I too felt extremely fatigued today and I think it might be a accommodation of things, for me its mainly underlying anxiety and biological factors playing a huge part in my physical symptoms of depression.
I think even though we didn't feel so good, its during these times we need to make sure we are still eating well. I think its worthwhile to get a referral to a clinical dietitian because diet plays a huge part in the healing/recovery process.
It is quite interesting to research about the brain and what is made up of and what we need to make sure the brain stays healthy. We need carbonhydrates and omega 3 in diet, plus other things too and make sure you drink plenty of water and exercise to get the oxygen flowing through the body.
