At times I feel mentally depleted. I feel tired and my mind is everywhere. God reminded me that in his presence, there is joy and that I needed to have an extended one-on-one session with him. He also gave me the text in Matthew where he was led into the wilderness and Satan tried to use overthinking as a form of mental torment to mentally deplete him. He resisted with the word. And the angels of God ministered to his spirit. God says he wants to do the same for you! When you feel mentally or spiritually low, it's a clear indication that you need a recharge, by way of the presence of God.
