Brief Answer:
Further work up required
Detailed Answer:
Hello
Thanks for the quick reply
The hypoglycemic episodes are something that needs further work up, 
Metformin does not cause hypoglycemic episodes and morever you are not even taking them. Higher 
testosterone levels could be part of your PCOS but again that does not explain the hypoglycemic episodes or the muscle issues. So before calling it an anxiety related issue I would like you approach a doctor with the following suggestions of mine
1. Please get a Serum 
Thyroid stimulating hormone, Serum electrolytes including potassium, calcium and Serum 
Cortisol test done. If the lab has provision to test for serum 
insulin levels then please get that done as well
2. I would like them to do a 
glucose tolerance test to check for sub normal increase in glucose levels
3. If the above tests are normal, I would like you to undergo tests for nerve conduction and a muscle biopsy ( it is a minor OPD procedure) to rule out nerve and muscle involvement 
Vit D is probably low because of less exposure to the sunlight, please take Vit D supplements. Vit D deficiency usually causes fatigue, muscle and 
joint pains.
I hope I was of help, if you have any further queries please get back to me
I wish you good health
