Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not to worry much. There are certain things you should know. Fear is fearing something which is present. Apprehension is imagination. Anxiety is creating the symptoms of fear with the help of apprehension, means anxiety is fear without the presence of the reason. Obsession is repeated unnecessary behavior. Now, in your case, pulse and heart rate is a bit high because of your apprehension and anxiety. Checking pulse is not a bad option, because you have the problem here. What you have to change is, the anxiety and apprehension. You should tell me what are the causes of your anxiety? For how many days it is present etc. For now start with drinking plenty of water, meditate whenever you can and deep breath, exercise daily. Keeping yourself busy helps in overcoming thoughts. Thoughts are there to come and that is the duty of the brain. let the thoughts come. You need to divert the thoughts to more priority ones. Means be busy and divert thoughts.
