Ryask,
I was in the same situation as you, feeling like i was made miserable so I would quit.
First of all, you love your job, so I wouldn't let anything get in the way of you keeping it.
If you are emotional at work, you might need a med adjustment...I did, and took a short leave to get them right.
In the meantime, I did all I could to fly under the radar and just do my job without getting myself into situations where I would exhibit behavior that called attention to myself.If your superiors don't have a reason to notice you, chances are they are so busy with other things that over time they will forget about how you acted before.
