I sometimes get *physically* anxious — not having any anxious thoughts per se, but I get cold, my whole body tenses up, and the only way to feel better is to keep moving and keep my heart pumping fast. It happens almost every time I smoke marijuana as well. 

Are those normal symptoms of anxiety, or is it a sign of some heart issues too? I haven’t really found anything online that describes the feeling. 

I’m small - 120 lb male, so I feel like the size of my heart may have to do with it. It’s like the anxiety a rat would have or something. 

Thanks if anyone has any insight!
