I can't stop obsessing over something that happened a few days ago. My emotional reactions to things last for days. For some reason just thinking about this situation makes me want to cry, even though it's been long over. I know this situation won't matter in a month or 5 months or a year but right now it just seems so urgent. I hate how my fight or flight senses are always going crazy. Please tell me I'm not alone in this experience.
