Depression is real and is often not diagnosed well enough. It's a good thing though that people are starting to open up a bit regarding this (due to the stigma involved when people openly talk about these issues), because it's always best to have someone to talk when depression happens.
Indeed its best to have someone you can open up with regarding of what you've been going through. That is for them to understand your current situation and can give you advice and encourage to think positive. Depression is a serious mental/emotional problem that should be address accordingly to avoid worse situation.
