I have quite a lot of food intolerance and I can only eat very low carb.
I had a lot of symptoms that you are experiencing.
Which alleviated when I had been eating hardly any carbs or sugars at all!
Diet is so important to your mental state. A lack of or an excess of hormones can cause the symptoms you described.
I know not of lymes disease, so cannot comment on the effects of that combined with your intolerances.
I had a real struggle to get through my ' hypo hell' because doctors didn't have a clue what was going on. You cannot give up, you must with the help of a blood glucose monitor try and get better control. You must try and get knowledge of what treatments are open to you. You must find an endocrinologist who can help you.
