EnjoyLife, thank you! Right now I don’t have a doctor, but after doing some more digging and talking to my family, especially my oldest daughter, I am not making the change to keto. It sounds like it could potentially be pretty dangerous for me with my low blood sugar.
I am going to make some dietary changes though after talking to my daughter. About a year ago she was diagnosed with a MTHFR gene mutation. I did a little research for her, but didn’t really give it much more thought outside of its affects on her (it is a cause of miscarriages). I just never really made the connection. She, on the other hand, did make that connection. She has spent the last year learning how to live with it and also how it has probably been affecting our family for generations. 
Her doctor’s told her that without seeing me they can’t be certain, but they suspect that at least some of my trouble with the chronic pain, fatigue, brain fog, depression and anxiety, and all the rest can probably be tied back to that mutation. Other factors in my life, of course, play into it all as well, but that missing gene is likely the starting factor and the others just built on top of it.
So, as a start I am making some changes to how I eat. In theory, it is easy - in practice, my daughter said it is sometimes a challenge. The basic idea is that I switch from a “white flour, enriched” diet to a non-enriched diet, since that missing gene affects the bodies ability to process the synthetic form of niacin that is put into everything that is enriched. Since my body can’t process it, it builds up in my body causing trouble.
She did warn me though that likely at this point I may not see much “improvement” in my pain and such. My body is reacting to the damage that has been done and that damage may not be repairable, but we hope that with the diet changes (and eventually I will add in some supplements) that we can slow/stop further damage.
