Two principle forms of diabetes: Insulin dependent (type I) or juvenile onset diabetes occurs where individuals produce little or no insulin.  Type II (adult onset) diabetes is where they don't produce enough or are unable to use what insulin they have.

Symptoms for type I usually arrive quickly and strongly: frequent urination, extreme thirst and hunger, weight loss, and fatigue.  Often will have frequent infections and bruises .  

 Diabetes and psychological distress - Fear is common with concerns over possible amputation, CHD, nephropathy, neurological problems, & retinopathy (blindness).

Hypoglycemia (low blood sugar) occurs and may lead to fatigue, disorientation, confusion and negative mood.  This may also result in anger and confusion.

Depression and diabetes - depression is twice as common among diabetics than the general population. They may feel isolated and unsupported in addition to the fact that hypoglycemia leads to depression, sometime through a vicious cycle of worsening.

Helping people cope with diabetes - two major goals here: to encourage adherence to medical regimen and disease management, as well as alleviating psychological distress.

Cognitive behavioural therapy (CBT) is also used to help with depression, since anti-depressants have negative side effects.

Educational and support groups are also are beneficial including dietary information and patient support groups.
