Is It Chemical Or Is It Me

I have noticed over the past couple of years that I have an ebb and flow of emotional sensitivity. I am struggling with figuring out what it really is. If my boyfriend makes a sarcastic remark to me one day, I might come back with something equally spicy and joke around with him. Another day, that remark could have me in tears, even though logically I know he wasn’t being mean, wasn’t try to attack me or anything. My thoughts will immediately dive into how crying doesn’t make sense in this situation, what actually happened to get there. Usually, I don’t know.

I have these very irrational feelings and wonder how off my hormones are to take me to tears over nothing. Or, am I denying my thoughts. I know you are not a doctor, but any advice you have on noticing the difference between hormonal, like PMSing , feelings versus doing the model and thought provoked feelings is appreciated.
