My humble suggestion…
Let’s all have an optimistic view of our Rabb, and believe that our fast this Ramadan will indeed wipe clean our record of sins. Let’s begin Shawwal hoping that we have been forgiven, but assuming that anyone who has sinned against us has also been forgiven, and let’s try to deal with them on this basis.
Let go of any grudges or resentment you may have because of wrongs they have committed against you in the past, and start anew with them on a clean slate.
May Allah forgive us all, what we have committed, and what has been committed against us. Aameen
