Is there any way you can arrange to eat in another room, somewhere where your ex can't find you? I'd be very anxious in a situation like that as well. I'm sorry that he's being such a jerk, though the fact that he still eats in the same room may suggest that he has mixed feelings. Part of him wants to hurt you by spreading rumors, but another part was serious about maintaining a post-breakup friendship. Is he nice to you during lunchtime?

If it's any consolation, drama can keep life interesting. I never had any drama in high school (due to anxiety keeping me from getting really involved with other people), and sometimes I feel like I've missed out on a major life event.

I hope that the med change helps you. How are you doing with the paranoid thoughts and hallucinations?
