Who diagnosed you with panic attacks? Who told you you're having seizures? Panic attacks, no matter how severe, are nothing like seizures. Panic attacks include many symptoms, like trembling, lightheadedness, numbness, chest pain, and more - but they're nothing like seizures and they have a totally different cause than seizures. Although I know how terrible a panic attack can feel, they are NOT physically dangerous nor are they causing any damage to your body. However, panic attacks are miserable to live with so follow the advice of your doctor, including medication, and they can become a thing of your past. Good luck.
