Managing Chronic Fatigue: Seeking Advice and Support

I am new here & have been dealing with CFS since 2018. I have an internist that sees me every 3 months mainly for Diabetes 2 but will TRY to answer about CFS but mainly says work on what is most important at that given time. So mostly any MD's I have seen have no clue what to do for me. In reading everyone's posts I see depression is a big factor. I was never confirmed about that. Although in 2010 I remarried after 35 years on my own (I married right out of highschool to a verbally & physically abusive man). In 2012 I found that my husband was seeing other women. I was devastated,! So maybe I am in denial as far as depression goes. Regardless I am on a mild med. Mainly I have a routine with my meds and vitamins and supplements. I work hard to eat healthy but I am pretty sedentary. My chronic fatigue syndrome started out with me feeling unsteady and like I was losing the ability to walk. I am retired and live at home with my dog. My second husband and I are still married. He lives hundreds of miles away but comes to visit every other month. I haven't gotten divorced because it was hard enough for my first divorce! My second husband does help me a lot when he comes in. I need anyone's input as far as what I need to be doing because what I'm doing just isn't working. My quality of life really sucks right now. I'm sure that has to do with totally me.
