Do we need to repent of our repentance?

In 2Corinthians 7:8-13 Paul writes -

8 For even if I made you grieve with my letter, I do not regret it though I did regret it, for I see that that letter grieved you, though only for a while.
9 As it is, I rejoice, not because you were grieved, but because you were grieved into repenting. For you felt a godly grief, so that you suffered no loss through us.
10 For godly grief produces a repentance that leads to salvation without regret, whereas worldly grief produces death.
11 For see what earnestness this godly grief has produced in you, but also what eagerness to clear yourselves, what indignation, what fear, what longing, what zeal, what punishment! At every point you have proved yourselves innocent in the matter.
12 So although I wrote to you, it was not for the sake of the one who did the wrong, nor for the sake of the one who suffered the wrong, but in order that your earnestness for us might be revealed to you in the sight of God.
13 Therefore we are comforted.

Between 1 and 2 Corinthians, the Apostle Paul has written a letter (which is now lost) that has grieved the Corinthians, but only for a while. It is not clear, but it seems the issue was about the sinning brother from 1Corinthians 5. By the instruction of Paul to the church at Corinth, they were to deliver this man to Satan, the church being purged by casting the man out from among them. From 2Corinthians 2 we see that the man repented, but the church has not accepted him back into fellowship, which caused him to be overwhelmed with excessive sorrow. They were to forgive and comfort the repentant brother instead, just as the apostle Paul did. It is clear that Corinthians were very slow in imitating Paul in forgiving the once horribly sinning brother, and perhaps doubted Paul's wisdom in this matter. Now, Paul's apostolic authority is in danger of being rejected by the Corinthian church. So Paul has a new fear for the church. The fear being - will the 'super apostles' that are trying to disturb the Corinthian church gain a listening ear of the Corinthians, and turn their devotion from Christ to a false gospel? This is why Paul wrote the strong letter to the Corinthians, that has caused them grief, but only for a while. The letter has caused the Corinthians to repent of their doubt and rejection of Paul's apostolic instruction, regarding the once sinning brother. And once again the church is earnestly longing, mourning and being zealous for Paul, the Apostle of Christ Jesus.

What is repentance according to God? It is grief produced by looking at our sin from God's perspective that results in life turned back to God. Any sin, is wrong done against God, first and foremost. Not, what pain has sin caused me, or another, but how have I offended God in my wrong action. Looking at self and others will produce only worldly grief like that of Judas, who hanged himself afterwards, which ultimately leads to death everlasting. But Godly grief, sorrow according to God produces a repentance that leads to salvation (and that) without regret. Godly grief changes not only person's mind about sin, but direction in life. This grief acknowledges its sin against God, but also receives God's provision for the forgiveness and cleansing of the sin. There is no more regret after we have confessed our sin, AND have received God's forgiveness and acceptance through the death of his Son Christ Jesus on our behalf.

Forgiven and set free to willingly trust and obey our merciful God.
