Philippians 4:4-9, in my own words.

Rejoice in the Lord always; again I will say, rejoice.

Fight for joy all the time, every day, in every waking moment. Don't find joy in things, but in the Lord. His joy fills you better than any earthly thing, so fight for joy in the Lord.

Let your reasonableness be known to everyone. 

Show people you are fighting for this joy in the Lord through your lifestyle. You are not fighting them, but you are fighting joylessness. Be generous, be kind, be loving; let everyone see and taste of the amazing transformation the Lord has brought about in you.

The Lord is at hand; do not be anxious about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus.

The Lord is not far away. He is right here with you, every moment of the day. Since He is right here, pray. Pray for your needs, and for others' needs. Be thankful to God in advance! This is the Creator you are praying to, and He already knows all your needs before you pray! Your praying points others to Him, so be specific and dare to pray audaciously! God will honor your faith by exchanging your anxiety for His peace, which will anchor you in the storms of life. You will be able to stand firm and unshaken, though you may be in dire straits.

Finally, brothers, whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is commendable, if there is any excellence, if there is anything worthy of praise, think about these things. 

So, think positively! Your optimism is not founded on wavering hopes in man-made things or fortuitous chance, but on the Man who loved and died for you. If His Word were not true, then all is lost. But He is God, and His Word is true. Fill your mind with His Word, all His promises made to you and all who believe. Do this daily, arm yourself with the right words for each circumstance so that when they come, you will be ready.

What you have learned and received and heard and seen in me—practice these things, and the God of peace will be with you.

Haven't you an example in me? Do what I do, and I am sure that God will show up in your life too!

Postscript: At the time of writing this, I am at my first-ever Week 10 of Term 3 as a primary school educator. While this may not make much sense to you, I am marking the time for my future self to remember how much anxiety and fearfulness I faced. I don't want to live like that any longer, because it is joyless. I refuse to live joylessly. So before you judge my paraphrasing, please be considerate for my struggle.
