Have you received a letter of concern, spread it out before your Creator.
I am reminded of a story in the Book, where a King named Hezekiah received a threatening letter from another king, more powerful than him. King of Assyria demanded worship and even warned King Hezekiah not to trust God. This was said of Hezekiah before this incident "Hezekiah put his whole trust in the God of Israel. There was no king quite like him, either before or after. He held fast to God—never loosened his grip—and obeyed to the letter everything God had commanded Moses. And God, for his part, held fast to him through all his adventures".
The King's servant had a very humiliating letter for Hezekiah in his possession. He started making threats speaking loud to everyone's hearing. “Please, speak to us in the Aramaic language. We understand Aramaic. Don’t speak in Hebrew—everyone crowded on the city wall can hear you.” Defiantly, the Assyrian King's servant replied ''We weren’t sent with a private message to your master and you; this is public—a message to everyone within earshot. After all, they’re involved in this as well as you; if you don’t come to terms, they’ll be eating their own turds and drinking their own pee right along with you.” What a frightening message both to the King and his subjects.
The taunts did not subside but increased, "Don't listen to Hezekiah's lies, he cannot save you, has anyone ever escaped from the hands of Assyrian king?' In fear and trepidation, the people rushed to Hezekiah with the news of the threat. Isn't this similar to how we get worried when we receive news regarding situations we can't handle. We panic.
When Hezekiah the King heard it he became distraught too but he did something that most of us don't do instantly. he went straight to church and spread the letter before his creator. He received a word of comfort from a prophet and strategy for dealing with the situation. 'Be not afraid of the words that you heard, with which the servants of the king of Assyria have blasphemed me. Behold, I will put a spirit in him, and he shall hear tidings, and shall return to his own land; and I will cause him to fall by the sword in his own land'. The opposition will hear a rumour and return to his abode.
Only trust in a power higher that you can make it happen. This is why we should not rely on our own abilities but when we believe what the big book says that 'greater one lives is us', we should not exhibit fear. Fear paralyses. Faith builds up. We need not fear but believe like a child. It is sometimes difficult because we are used to seeing before we believe. I sometimes say to people you sat on that chair but don't know whether it is safe to do so.
In conclusion do not let fear of the known or unknown overtake you. Believe you have a greater power in you, able to give you the strength to cope. Take your concern to your Creator, he has solutions awaiting you. Let that confidence build up you up. There nothing happening to you that's never happened before. You have the power to overcome.
