Depression is unyielding is it not?
I mean we take medication for the mental illness don't we?
But, don't lose hope. There is a hope a Godly hope found in the bible: https://www.biblegateway.com/passage/?search=Psalm+143%3A7-8&version=NIV.
God's love is loyal like you would not believe: https://www.youtube.com/watch?v=bU4JJpoS8Ec.
These links (and another pair of them) will help you if you are depressed at any time.
Hope this helps you understand what depression can do to you if you don't know how to deal with it properly.
