Feeling betrayed still

Hi all. I am having anxiety for a different reason that I don’t want to get into, but I feel like if I can chip away at the edges it will help with the whole. Several years ago when I was at work, I had clients say bizarre or threatening things to me. I talked to the therapist about it and one therapist told me she didn’t think that really happened and I can’t even remember what the other therapist said - just glazed over it though. I think I just want someone to validate that it happened and that it should not have. Thoughts? Why would people do that and do I just have to put up with that type of bologna? Does this happen to everyone?
