A the age of 24 years a man should feel fine, but you are not in that category. You are describing excessive sweating, blotches under the eyes, at least one episode of your heart racing, blurry vision, and generalized weakness. You also report chest pain and discomfort in the left arm, weakness and faintness.
Too much sugar in the system is diabetes, but I gather that is a chiropractic diagnosis without diabetes.
I'm not sure what is going on. You don't mention your work, your habits, your alcohol intake, drugs you are taking, your past history or your family history. The nature of the chest pain you are describing would be important. The major symptoms you are now experiencing appear to be daily weakness and faintness.
Reading your story, it seems to me that your major symptoms have changed over time and that your were feeling OK before this sequence started, and therefore you should definitely check with your doctor again. He may want to do certain blood tests and may want a dermatologist to check the rash under the eyes.
Please keep in mind that I am unable to diagnose medical conditions online.
