Whatever you are facing today, remember, that David did not fight his battles the way his enemy, Goliath, fought his battles. David did not use the customary weapons (Saul's armor) or tactics but relied upon the Lord and his past experience with the Lord. I would encourage you to read God's word and come to know him in his deeds throughout salvation history. Don't pay attention to negative input and don't be afraid of what your Goliath's are saying. The battle belongs to the Lord.
