Never be ashamed of your emotions. God is emotional. You are made in His image.
When you get into His presence, you can say anything you want. Any way you want to say it. God is simply thrilled you have come for a visit.
“And at the evening sacrifice I arose up from my heaviness; and having rent my garment and my mantle, I fell upon my knees, and spread out my hands unto the Lord my God,”
(Ezra 9:5)
