I am a 36y/o male. I have had panic attacks now for almost 3 years. They usually come in the form of an extremely unsettling felling in my brain which my panic interprets as I'm about to pass out or worse, have a seizure. I have no prior history of seizures but my brain just feels wrong. I have also had incidents where i thought forsure i was having a heart attack even going to the E.R. twice only to be told i was fine. My doctor has perscribed me Lexapro but because of my extreme phobia of seizures and this messed up feeling in my head, I'm terrified to start taking the meds. Please help. I need to knkw if the feeling in my brain is common for people suffering from anxiety disorders. Thank you for any feedback.
