Hi Wissam, I'm so sorry to hear you are feeling this way. As someone who has suffered from panic attack disorder for 10 years I can tell you that until you accept that the symptoms you are experiencing are anxiety related, you will not get any relief from it. You have to accept that those sweaty palms, dizziness, rapid heart..it's all from the panic attack. If you've had tests and they've confirmed you are fine, then you need to accept that you have panic attacks. And from there, you can learn to deal with them. Whether that is through medication or therapy or a combination of both. It always helps me to know I'm not alone. Remember, no one has ever died of a panic attack! I wish you all the best!
