How do i know if i'm suffering from depression or am just stressed?

Low self esteem: Depression almost always includes low self esteem, both conditions can share sleep and appetite changes, loss of energy, irritibility. Suicidal thoughts more likely with depression. And stress may lead to depression.

Depression signs: Include being down most of the time, loss of interest/pleasure in activities, unintended increase/decrease in appetite/weight, sleeping more or less than usual, being agitated or lethargic, feeling worthless or inappropriately guilty or self critical, having difficulty concentrating or making decisions, & thinking of death & dying. Talk to your physician or a mental health professional to decide.
