I'm not sure why your post asks why others are treated better than you. You haven't given any example of others being in the same situation who have been treated better than you. If this is about the job that you got fired from and being told to stay away from that supervisor, that isn't treating you worse than others. That's the punishment you get for behaving badly even after you were warned multiple times. There are consequences for breaking the rules. Whether or not you agreed with the rules and boundaries set down for you, you were required to follow them by your job, and you chose not to. That's why you were prohibited from seeing this person. They did not walk away from you. You created an untenable situation for them. They were not obliged to suffer your stalking behavior.

You keep asking this question thinking that the answer is going to change. The fact of the matter is you are responsible for your own behavior, and you chose to break the rules. You now have to deal with the consequences. It does no good to dwell on it and try and change the facts in your head to make you feel better about it. Accept that you made a mistake, try to learn from it, and move on.

Continuing to obsess over it will only get you in more trouble.
