Tell God how you feel.
Psalm 6:2 “Show me favor, O Jehovah, for I am growing weak. Heal me, O Jehovah, for my bones are shaking.”
In psalm 6 David was completely honest with God and about how he truly feels. In my time of needs all I do is pray, when you cannot sleep pray to God and ask him for peace. When you are angry or sad ask God to lay a hand on you and to take away any fear in your heart and to calm your mind. Your prayers don’t have to be perfect! I pray with tears in my eyes and snot coming out of my nose! Sometimes I scream in my pillows when I am asking God for mercy or when I am frustrated. God is your father talk to him! He is listening to you! He understands you better than any other human beings can.
Be honest with God! Never lie and have faith.
