You may not be treated equally or justly in this world. Rest assured, it's short lived. As, ALLAH says in the Quran, "not a soul will be dealt with unjustly".
Be patient and have belief in ALLAH. On the day of judgement every single body will be treated justly even if the deed weights as much as a mustard seed, Justice Will Be Served.
We shall set up scales of justice for the Day of Judgment, so that not a soul will be dealt with unjustly in the least, and if there be (no more than) the weight of a mustard seed, We will bring it (to account): and enough are We to take account.
[Quran 24:47]
All of us have had our own share of been treated unfairly or unjustly. What does ALLAH say when that happens? ALLAH doesn't say just Forgive, He says "Forgive and Overlook". Throughout the life of our beloved Prophet Muhammad(pbuh), we have seen numerous examples. He even forgave the person who killed his daughter.
So, always remember " Forgive and Forget"
