Have you said you were diagnosed with ASD and BPD in an older post? I am trying to understand more about these diagnoses and how they affect you. It is interesting to see how both of these may be at play in your thoughts and behavior. (Though I feel for you in having these).

Naive question: When you apply for a new job, does the manager tell the new company about your problematic behavior at the old job? Do unsuspecting companies keep hiring problematic employees without a clue?

Although your behavior seem to be disruptive and stressful to you and everyone else at your job, it could be dangerous. Do new companies unknowingly hire dangerous, stalkers because the old manager is not allowed to reveal this important information?
