((seraphic)), sorry to hear you are out of sorts this way. I can't say if you have PTSD or not, but what I can say is that a person "can" experience a delayed reaction like that, a lot depends on what was said that deeply upset you too.

If you want to take a shower do so, the warm water will help relax you too. Just write down "if you can" what bothered you, do you have a journal? It might come to you later on where you can put it all together. No one is hurting you "now" remember that, you just got triggered, that's all.
