Psalm 69:13

But as for me, my prayer is to You, O Lord, at an acceptable and opportune time; O God, in the greatness of Your favor and in the abundance of Your lovingkindness, answer me with truth (that is, the faithfulness of Your salvation).

We all have those moments of intense, needful prayer, crying out to God for help only He can provide. God is faithful when we pray in faith for our needs. He alone knows our fears and circumstances, and He alone can comfort us during the trial.
