Don't feel bad, we all have bad days, sister. You did the right thing in listening to what the Lord was urging you to do, in apologising. Keep walking the good walk and learning how to include Him in your life more and more.
It took great courage on your part to apologize. You definitely extended the olive branch and the Lord is always testing our character to see if we will be obedient to his calling as we grow and learn new lessons that the Lord has for all of us. I am sure God is smiling down upon you today and is very proud of you my dear sis....
