Hi everyone, this all started for me over 3 months ago. Never really had any problems, one day out of the blue my heart was racing felt like I was going to pass out. I immediately went to the ER where they said you had a panic attack. I was terrified because obviously like everyone else I felt like I was going to die. I still wasn't completely convinced so I went for a second opinion got blood work done urine taken EKG chest X-ray & of course they didn't find anything. I was honestly hoping they would find something because the way I felt just wasn't normal in my opinion. You start convincing yourself you have cancer. This isn't a life to live for anyone. I was prescribed celexa but haven't taken them yet. Has anyone took this particular medication? Reviews please & if you experienced any weird side affects.
