please help me figure out what is wrong

3 days ago out of nowhere i got extremely lazy and the only thing i could do was just sleep. i would get really hot one second, then i would get really cold. i've only eaten one taco cause i dont think i can hold food down. i guess you can say i'm kinda scared to eat. i feel extremely weak, and light headed, i really can't focus much, my mind feels foggy and my left hand gets real tingly and my fingers go numb for a bit. and i've noticed today that my tastebuds can't really taste much.

Of course only a dr. can dx what is going on.  There are several things that come to mind.  The first thing is your thyroid.  If you are hypo, that can make you very tired, and cold, etc.  Hormone fluctuations can cause similar symptoms.  High/Low blood sugar can also cause simliar symptoms.  

Do you have any pain assoiciated with any of this?

If you have had any dental work done recently you could suspect mercury poisoning.  The amalgams they use have mercury in them.  If you get too much mercury in the body you will see the sympthoms you describe.  The book "Prescription for Nutritional Healling" will tell you the supplements and diet you need to get the mercury out of your body.  You might want to consider the Paleo diet which has shown good results in treating autoimmune diseases.
