God cares about your mental health. He wants you to feel joy. He cares deeply about you.
When you practice gratitude. You are giving God the glory. You are acknowledging God is providing for you. Practicing gratitude takes just a few minutes every day, to FEEL thankful for what you normally would take for granted.
The more you strengthen your gratitude muscle, the more you will feel the joy that God promises all of us.
Hope this encourages you!
