Worry: Past & Future Psychology

Worrying (about one’s future) –> causes “anxiety”
Worrying (about one’s past) –> causes “depression”

So, that’s why He instructed us “not to worry”:

“Therefore I tell you, do not worry about your life, what you will eat or drink; or about your body, what you will wear. Is not life more than food, and the body more than clothes?” – Lord Jesus Christ (Matthew 6:25)

P/S:

Remember, worrying will ‘not’ solve any problem but it may cause either “anxiety” or “depression” as explained above.

Solution?
Pray for the faith to endure ‘whatever’ that comes your way by His Will as this verse points:

“No temptation has overtaken you except what is common to mankind. And God is faithful; He will not let you be tempted beyond what you can bear. But when you are tempted, He will also provide a way out so that you can endure it.” – apostle Paul (1 Corinthians 10:13)
