My heart goes out to you. I have experienced CF during my spiritual ascension. I currently have chronic pain (undiagnosed fibromyagia) and besides going through a lot of emotions and changes (internally mostly), that is my only ailment right now. Though I've been diagnosed with a mental illness in the past, I do not consider that to be accurate. I have been through a ton though, and many traumas in my life, so I found Lastars comment about that interesting. I also agree with Good Energy about the importance of energy healing. Because traditional medicine today is very limited and only encompasses one aspect of the human body...the physical, tangible part. If traditional medicine is not able to help you at this time, don't give up. Keep searching.
In my opinion, everything that ails a person today (which includes symptoms, illnesses, diagnoses, etc.) are actually a surface symptom of an underlining issue/problem. Western medicine "treats" symptoms, not what is causing the problem, and that can often lead to more symptoms/problems, unfortunately
Just so you know I am sensitive like you and I also have the ability to see things from a multitude of perspectives. My "feeling" about your CF is that it is a symptom of past problems that you still carry with you in your mind today. And these problems, when not released, continue to build up in the person's mind and heart, and eventually there is no more storage room left, so in order for the mind/heart to continue on and deal, they begin to store the negative thoughts/feelings/memories/resentments, etc. in the body, and that is when physical illness is a bi-product of mental/emotional distress. The mind/heart can only handle so much pain.
Your chronic fatigue, food sensitivities, and any other ailments you are experiencing should be viewed as a "red flag" so to speak to look within and realize the negative things you've been holding onto and release them.
Early childhood trauma (or any trauma a person experiences) and all other negative life and people experiences, get stored in our mind/heart memory until we deal with them (feel, accept, forgive, and release). You have a lot of pain inside you right now and it's now showing externally.
The CF I experienced recently lasted 2 days (though I've experienced needing huge amounts of sleep before). I felt completely run-down, depleted, as if the world had sucked the life out of me. I realized it was past hurts I was holding onto, plus other things that I'm still working on accepting/releasing
I think you can continue to look to the outside for the solution to your CF, forever, but that will only cause more distress in your mind, adding to your mind/heart pain which adds more physical symptoms as well.
If I was a doctor (or just a really good friend), I would suggest that you give yourself a break trying to figure out what's wrong with you, and forgive yourself and everything and everyone from your past (I know, that sounds like a lot, but work on it a little each day). Practice having compassion for yourself, the kind that you so easily show to others. Because, truly, you are hurting on the inside, and it's showing on the outside.
So, my "prescription" for you is:
Relax, self-care, and joy (based on your tastes, such as: read, walk, nature, animals, art, music, meditation, yoga, cooking, playing, baths, hugging yourself, good cry, good laugh, journaling, etc...).
Your body is saying STOP and take care of you. You have been ignoring/neglecting something about yourself, but once you tend to it, you will improve.
And as far as not being connected spiritually, I went through a dark/cold time as an atheist, then my doctor (who treats symptoms with nutrition and lifestyle changes) recommended Eckhart Tolle's "The Power of Now." The logical/realist/left-brained me was able to grasp onto the "proof " I needed that spirituality did exist. Though for several months I had spiritual beliefs and I believed, I did not FEEL spiritual...I did not feel the "magic" in the world, so to speak. But when I practiced grounding myself (energy flow) with the additional help of an energy healer, a blockage in my energy flow was cleared and I suddenly felt spiritual, like a light switch had been turned on in me. That was the moment of my spiritual awakening.
I feel that so many people have experienced trauma and pain in their lives and their hearts close off. All the negative experiences get stored in the body if not released and this creates blockages and illnesses and prevents people from even experiencing joy.
Look within for your own truths. They are there. I wish you the best. And remember that we have to go through the darkest moments to get to the light. It is the only way.
Love and light~
