Anxiety symptoms not going away (palps)

Hi, I'm a 17 year old male... I've been suffering from anxiety since lockdown... It is health anxiety, typically my heart beats harder and i feel every pulse in my chest, neck, head, fingers etc... I also feel some jerks in head... I know it is anxiety... I am trying to cope with it since last few weeks, I'm off of any meds(homeopathy)... I practice meditation too but it may not be showing promising results right now... My main concern is the pounding heart beat i get... It usually is faint in the morning and increases in the afternoon then again decreases till the night... But it happens all the time... I have done ecg and x-ray, it was fine, figured out it is anxiety... But how long is it going to take? This wastes a lot of my time as i am unable or unwilling to concentrate on anything due to this... My body is still shaking from those beats when i write this.. The thing that makes me sad the most is when i remember the time when i was completely fine... Please help. Thanks.
