I really feel for you so much regarding the trauma you've suffered, the challenges you've faced over the years and, now, CFS.
My friend's in the process of elimination and waiting phase of being diagnosed with CFS. She's now struggling with depression on top of it. As I mentioned to her 'It's important you say 'My body and mind have been chronically exhausted over the years and now I'm feeling it', instead of I'm hopeless and can't do anything'. She puts her symptoms down to the crazy hours she worked in a job she just resigned from but I beg to differ. For the past 5 or so years, since she split from her husband (who was an emotionally abusive and exhausting guy), she's faced the recurring stress of 'Where will I get the extra money from to pay the bills ? How do I deal with an ex who doesn't seem to give a damn about the kids? I feel like I'm doing a lot of this alone!'. The list goes on. With each state of hyperactivity, the vascular system, the endocrine system, the nervous system and all the other systems go through, they're put under pressure and can be exhausted, depending on the severity and duration of the stressors. Do this again and again and again over years and the systems are chronically fatigued through reoccurring states of hyperactivity. Eventually, the body says 'Enough is enough!'
The next stage involves restoration. Kinda like saying to the body 'Okay, I'm going to be really nice to you now as you recover'. My friend is going through this stage and it's definitely a multi-faceted stage. Not only does it involve gentle kindness to her body through a change of diet, some gentle relaxation , very low level exercise (that may only last a few minutes at a time), music therapy, aromatherapy, bath time therapy etc, this has proven to be a time which has involved a lot of letting go. She's held onto a lot of resentment, anger, disappointment, fear and fluctuating self-esteem over the years and these factors have also exhausted her.
When dis-ease becomes so great that it leads to disease, it's at this stage that we're feeling the dis-ease. It can become physically debilitating.
By the way, after some months of kindness to herself, my friend is now looking to go back into the workforce. My advice 'You're body may still be in recovery mode, so don't be too quick to begin exhausting it again'. She has support in the meantime.
Delly, this is a time of kindness, to yourself. You deserve it. You've been through so much.
