When you have times of feeling nervous, frightened or anxious stop and put your mind on thoughts of God and His love for you.
Read: Philippians 4:6-7
6 Don’t worry about anything; instead, pray about everything. Tell God what you need, and thank him for all he has done. 7 Then you will experience God’s peace, which exceeds anything we can understand. His peace will guard your hearts and minds as you live in Christ Jesus.
