Anxiety can mimic a lot of things inside our body. You have to remember that the mind controls everything and processes everything you experience. I have had panic like anxiety where my hands felt numb, I felt like I couldn't catch my breath, a rushing feeling came over me, and my heart went haywire like it had a mind of its own. During this period of time I had a feeling of impending doom that was probably the worst of it. If you are asking if those are symptoms of an anxiety attack or generalized anxiety disorder, absolutely.
