I'm sorry for your losses, but depression in the context of the OP is a biochemical issue. What you're experiencing is profound sadness (I lost a brother to an OD, a nephew to rabies, etc., it sucks). Time theoretically will help heal your wounds but for many it's not that simple (as the article points out, we're still trying to figure it out). An incredibly bitter irony is that one can take steps to ameliorate the condition but when in the throes of it, finding the strength and ability to do so is incredibly challenging.
