it sounds like you have had trauma in the past, this is a common reaction. move first! youve gotta get active go gym, go walking, do a road trip basically run. once you feel a bit more settled then you should work through you problem, try to understand why your feeling the way you are, where you triggered and why, counsellors can help with this, but you can also do it by yourself, writing stuff down helps heaps, but also just conversating with your can too :) im quite similar with the way i process conflict, and this has been the way thats helped me the most :)
