I'm easily overwhelmed when having arguments or emotional conversations with my FP, who is my partner of 2 1/2 years. Almost every argument ends because I am unable to think straight-- usually conversations that have lasted less than 45 minutes or so. These never include yelling, threats, or other theatrics, but I almost always end up feeling like I'm drowning.

In more severe cases, my muscles feel physically weak, I'm hopeless, and can hardly understand what my partner is saying or formulate complex thoughts. Sometimes I'll ger a severe headache or neck and shoulder tension and feel like I have overwhelming and distracting high blood pressure. Other times I feel like I'm locked inside myself, move slowly, and can only speak in single words, often quietly. Sometimes I just... can't focus, till eventually I can't string together a sentence, and just kinda sit there and space out.

Does anybody else have these feelings, and what causes them for you?
