Yes God forgives, but how does one forgive himself?

So as far as I understand it, it is the case that if one prays, asks for forgiveness and repents and baptizes then according to most denominations and the Bible God forgives the sin one has committed. However what I can't quite wrap my head around is how to forgive oneself. Forgiving oneself in this context means (please use your own definition if mine isn't accurate enough): - Accepting that one has committed sin - Not beating oneself up/self criticism anymore because of the sin - No feelings of resentment or vengeance towards oneself - No destructive feeling of regret (still regretting but not the kind impeding with daily life or mental health) - No destructive guilt or shame (similar to regret: A little guilt/shame is not the problem, but to much of it risks mental health) While it might be easier to forgive single mistakes, it's a lot more difficult to handle character weaknesses or repeating sin. Is there any additional information about that? Summarized Question: - What does the Bible/the denominations say about **self forgiveness**? - How can one forgive oneself? - What steps can one do to forgive oneself? - Is the process to self-forgiveness fundamentally different for specific sins? - How can one forgive character weaknesses or repeating sin?
