Hi, so I have a question and my therapist is on holidays for 3 weeks so perhaps someone here can give me some perspective.
I notice that i'm utterly terrified of conflict and I'm kind off stuck on what to do with my body's reaction to it. The fight or flight response won't go away.

So what happened: Yesterday I visited a friend and I saw that one of her plants received water. Last week we discussed that it was already waterboarded and needed to dry out to survive. (I am an experienced plant keeper and she is not, so I help her out with her plant problems on the regular)
So I asked why she gave it water and she said it was dying because it was too dry. As soon as I responded with the fact that I think it had to be dried out for way longer and that it was still dying from the previous waterboarding, panick hit my body. "Oh no, we dissagree" 
I diverted to conversation to a different topic, but the damage was done. I couldn't (can't) relax since that moment. I feel constant racing thoughts and waves of anxiety through my entire body. I can't sleep, my muscles hurt and I feel like crying. 

I realize that this is a very extreme reaction to a tiny situation. We didn't even have an argument, we simply dissagreed and moved the conversation. Afterwards I even contacted her to make sure that I didn't mean anything in a bad way. 
Does anyone have tips to get this out of my system? It's driving me kind off nuts at the moment.
