The Emotional Roller-Coaster
Fasting can be an emotional roller-coaster. There are moments you feel like you are on top of the world and moments when you feel like an emotional wreck. That is why it is important during the fast to remember the purpose of fasting, to draw close to God.
As you continue on this journey allow God to show you things about Himself, yourself and how He wants to bring transformation in your life. Have faith that during this journey God is present with you each step of the way.
One last thought, any negative emotions you may be facing are lies. There is a presence out there who wants to confuse you and that is Satan. Do not believe the lies but trust in the truth that God is your father and you are His child.
Draw close to God and He will draw close to you.
James 4:8
