Do not leave depression if you are envious
If you carry envy in your heart for others, depression will remain with its darkness as long as the body exists. Wish the best for everyone around you. Some envy will afflict you if you see them superior to you, but do not allow it to burn your heart and break it with a sincere prayer. To them and say (O Lord, grant them success and increase their successes). If you reach this point, you will see that goodness has turned to you and may God grant you success, from where you do not realize it.
