In hadith Qudsi, Allah forbids us wrong one another, and tell us (as He always tells us again and again) about the reckoning :
On the authority of Abu Dharr al-Ghifari (may Allah be pleased with him) from the Prophet (ﷺ) is that among the sayings he relates from his Lord (may He be glorified) is that He said : My servants, I have forbidden oppression for Myself and have made it forbidden amongst you, so do not oppress one another. O My servants, all of you are astray except for those I have guided, so seek guidance of Me and I shall guide you, O My servants, all of you are hungry except for those I have fed, so seek food of Me and I shall feed you. O My servants, all of you are naked except for those I have clothed, so seek clothing of Me and I shall clothe you. O My servants, you sin by night and by day, and I forgive all sins, so seek forgiveness of Me and I shall forgive you. O My servants, you will not attain harming Me so as to harm Me, and will not attain benefitting Me so as to benefit Me. O My servants, were the first of you and the last of you, the human of you and the jinn of you to be as pious as the most pious heart of any one man of you, that would not increase My kingdom in anything. O My servants, were the first of you and the last of you, the human of you and the jinn of you to be as wicked as the most wicked heart of any one man of you, that would not decrease My kingdom in anything. O My servants, were the first of you and the last of you, the human of you and the jinn of you to rise up in one place and make a request of Me, and were I to give everyone what he requested, that would not decrease what I have, any more that a needle decreases the sea if put into it.
O My servants, it is but your deeds that I reckon up for you and then recompense you for, so let him who finds good, praise Allah, and let him who finds other than that, blame no one but himself. (Sahih Muslim, At Tirmidhi, Ibn Majah)
So when we commit wrongdoing, we should know the time will come for us to receive consequences of our wrongdoing.
Maybe Allah will punish us in this dunya, maybe in the grave, maybe in the Hereafter - this is all His Judgement.
And for those who wrong us, they should know, they too will receive consequences of their wrongdoings.
Remember the man in the story, who is arrogant belittling the other man who has less.
Al Mulk 2 : [He] who created death and life to test you [as to] which of you is best in deed - and He is the Exalted in Might, the Forgiving -
For as long as we are still alive, we can always repent and avoid committing more wrongdoing.
As for your situation, if you take time to reflect and be honest to yourself - you know what wrong you have done, what wrong others have done to you.
That is between you and Allah and those who have wronged you. On Judgement Day, there will be Judgement between Allah and you, and there is also Judgement between you and others.
