Stress related? More like jewish spike protein genocide related. The COVID injections cause your body to create spike protein. That spike protein was designed in a lab to have a higher binding affinity with European ACE2 receptors, and the least binding affinity with ashkenazi jewish ACE2 receptors. It travels to the heart and circulatory system (as well as your gonads and everything else) and causes your own immune system to attack the cells creating the spike protein.
