Know that Challenges, trials and tribulations are a part of life, especially in this age of Kali Yuga. Scriptures are filled with devotees who underwent one challenge after the other; but did not give up chanting his holy name, or their faith/trust in the Lord didn’t shake. That is in itself a form of gratitude. So remember that Disappointments draw us near God enabling us to trust him in greater degree. You are supposed to know that it’s just a phase..just a single phase.
