I've dealt with the same issue, and what helped me the most was Ivabradine taken with zinc. It helped control my heart rate, which in turn reduced the physical symptoms of anxiety. That alone made a huge difference in how I felt day to day because it helped also a lot with my sleep quality...it improved a lot.
An elevated heart rate can trigger anxiety symptoms because the body interprets an increased heart rate as a sign of stress or danger.
A fast heart rate can sometimes cause fluctuations in blood pressure, leading to lightheadedness or a sense of instability—both of which can be mistaken for an anxiety episode.
Some individuals (especially those on stimulants, high androgen doses) are more sensitive to adrenaline, meaning even a slight increase in heart rate can create a sense of restlessness or impending doom.
This is why medications like ivabradine, which lower heart rate without affecting blood pressure, can help break this cycle by reducing the physical triggers of anxiety.
