Really truly honestly believed my girlfriend of 4 years was cheating on me. She was not. I had never had a panic attack before but after noticing “missing condoms” (we used them a while back and I had just forgotten) I had one. I had no idea how to handle it and it didn’t help that she was out of town. Never felt that paranoid and alone before. We are still together and have been to couples therapy for a while now. Things are good but that has to be the worst emotional state I’ve ever experienced
