I keep on making up scenarios in my head about my bf leaving me or replacing me. It's getting me really worked up. I keep on imagining he's going to replace with me someone else. I'm getting so angry I'm stomping and throwing things about. I'm trying to relax with coffee and anime atm. But I'm wondering does this happen to anyone else and what you do to stop these thoughts. 
Sorry I just feel like talking about it might get it off my head a little.
