I m having worry and anxiety. I cannot attribute these symptoms to any specific thought or experience, in other words I cannot figure out why I am worried. While there could be underlying factors involved, I m generally worried about things I cannot control. All of this just makes it worse. I am shaking and my heart is beating rapidly. I tried breathing techniques and I attempted controlling my cognitive processes but this hasn t seemed to help. I m caught in a loop of constant stress and fear. I don t want to take medication for these symptoms. What are the best techniques I can use to calm myself down?
