<human>: Can you provide a brief overview of the text?

my entire life I was mentally, emotionally, verbally, physically and intimately abused. This left me with being triggered to some normal things that everyone does, in this case; shouting/increasing voice. 

All physical abuse I was a victim of and witnessed has always started with shouting/raising voice. So when someone does it, it affects me but when my partners do it I just break down. Today I was trying on a dress I ordered online, and had difficulty closing it. My partner offered help. As he was helping he said "the dress is not closing are you sure it's the right size?" And I said "this happened before, remember? I think it's about zip" but he kept bringing up "are you sure it's right size" so often I just said "Yes I'm sure it's right size" and just tried moving away to handle it myself to which he raised his voice/shouted "oh my god always like this" (or something similar which I can not remember). I said "please don't shout it makes me feel bad" and then he calmed down and tried to help with the dress again. He again brought up "I don't think it's the right size" to which I replied with just sighing and moving away and he started shouting some stuff and I just started crying. I left to bathroom for two minutes and when I came back he told me how I am always starting a scene and stuff like that. Some more stuff was said and I left home crying (in a totally foreign country that I moved to be with him). And I'm just all by myself now

I just want to know if I'm being overly sensitive?
<bot>: Boyfriend shouts at me and then says I am creating a scene for almost crying for getting triggered. Am I overly sensitive?
