Allāh ﷻ is King of Kings, Owner of the universes and He ﷻ has said that He ﷻ does not want to punish but wants to reward us. He ﷻ has given us these blessed holy days in which He ﷻ promises to forgive those who ask no matter what or how many their sins. So ask with a sincere heart and He ﷻ will change badness to goodness.
