Not quite sure what is going on..please help

I have had health problems for almost 5 years. I have a rhumatologist who thinks I have some sort of auto-immune disorder since my ANA is so high and I have vitilago spots on my torso. But, just recently I was diagnosed with chronic carbon monoxide poisoning which I think caused a lot of my problems including my adrenals to go out of whack. I saw a endocronologist who said I had hoshimoto thyroiditis but said my adrenals were OK. I saw an acupuncturist who said my adrenals are exhausted. I don't really know what's is right. I am hoping by posting my symptoms to this forum that someone can help me.

I get really dizzy when I eat things with medium to high glycemic levels, I aslo feel a wave of dizzyness when I put my head down or lean forward, Sometimes I feel week and my right hand trembles,I sometimes get sudden tingles in my hands when I feel a sudden wave of dizzyness, I also have blurry vision at times,I am very little energy, I have poor memory and I sometimes can't remember simple words, I have heart palpitations often and sometimes tachycardia. I had an episode last week where I got up in the middle of the night with intense thirst. When I got back to bed, i felt a burning sensation in my middle back close to my spine and then I started to see black. I sat up in bed and I felt myself going away like I was going to faint or die even. My husband said I had no color in my face or legs. It was very scary! The paramedics came but by then I was better. I had drank 2 glass of water with lots of table salt . That did the trick and I felt revived. I wonder if I caused this by eating sugary stuff before going to bed. I usually would never eat this junky cereal Lucky Charms but I had some in the house and ate a huge bowl. Now, just a few days ago, I did a little bit of Cardio exercise for about 5-10min and I crashed again. I had to take lots of salt to get back to normal. What is going on with me? I am also having a hard time digesting, I am a mess. What should I do? Night times seems worse or whenever I am at rest. Please help
