Depression - (This definition of depression is a definition made up IN MY OW WORDS.) Depression is a DISEASE of the mind that hinders your progress (on different levels and in different ways varying from person to person) and negatively effects you both mentally and physically. (I've chosen to use the word disease because people often seem to underestimate how serious depression can be.)
