PLEASE HELP I'M TERRIFIED GLUCOSE IS 35

So basically I have been having "issues for over a year" i was feeling generally unwell and extremely fatigued for months and all they found was High DHEA, low vitamin D, low Biotin and HPylori. So after a while taking vitamins etc I started to feel normal again- for 4 months. then last month it hit me out of nowhere. I got up one day and was so dizzy I thought I coulndn't make it down the street.

The dizziness was so horrible I couldnt get out of bed went to the doc and she found a blood sugar of 35. I have an appt. in 2 weeks but im scared I wont stay concious until then. I eat glucose tablets all day just to be able to walk around and stablize enough to go to work but it wears off rapidly and i am right back to feeling like i'm going to die.

Hypoglycemia not caused by dietary issues seems like a bad prognosis likely being a pancreatic tumor or MEN. Should I be worried - could this be cancer? I'm so so afraid.

PS My TSH levels are normal and no anemia or heart problems.
