I doubt those others who " look up" to your supervisor are staying late and in wait for her or coming in on their days off. I don't think you " look up" to her as others have said that implies respect and you are NOT respecting her boundaries.

When your shift is over go home. When you are not scheduled to work stay away from the work place.

Many here have suggested you speak to a therapist about this obsessive behavior of yours, it would be a good idea for you to do that. A therapist can explain to you in person why this behavior is wrong.
