Hi , welcome to health care magic.
The symptoms you are reporting may be because of low sugar, arrythmia
, panic attack
, or substance related. you might need to test at least blood sugar, ECG. Usually sleep disturbance (lack of feeling fresh in spite of good sleep), substance use and panic attack ( during which individuals feels that he is going to die here and now) and chronic problem (arthritis
in your case) are related or co-exist. For diabetes
to develop, family history of diabetes is not a must. Consultation with a cardiologist, psychiatrist
and your arthritis treating doctor might be needed. Wish you good luck.
