Anxiety: What you describe is consistent with anxiety. Your heartbeat is likely not visible but rather your breathing quickly. And the knot you feel is typical for an anxiety attack. It is a common side effect of stimulants and will pass and not return if you stop the medicine. The good news is that you are not damaged.
