Low Diastolic blood pressure (130/60)

Hi, I'm a 20 year old male, ever since my first panic attack 3 years back, I've started to feel my pulse all over my body and my body shakes on every beat of pulse which makes me uncomfortable. My usual bp is around 130/60. Ever since the incident, my Diastolic bp has always been low, even if my Systolic is in normal range. My body parts have also started to get numb quickly ever since that incident. This constant feeling of heavy beating of my heart always disturbs me a lot and makes me depressed. I want my life to get normal. Kindly help me and guide me on how to keep my diastolic bp normal, like it used to be. I take multivitamin and magnesium supplement s also... For better heart and overall health. I have tried many things but nothing helps. I want to know if there is any remedy that can calm my blood vessels to normal so i dont feel my pulse without any adverse side effects.
