I don't get it.

Depression makes zero sense. Even if there's nothing exciting going on in your life, you can enjoy life. Just being alive is fun. Even if you're ashamed of your past actions, just get over it because no one else cares.

Anxiety also makes zero sense. Just chill out and don't worry about everything, because nothing really matters except your inability to enjoy life, which you inflict on yourself.

Depression and anxiety seem to be the roof of other mental issues. So it all starts there. Just get over it and enjoy life!
