Hi, I am a 22 year old female with mild depression and anxiety. I was diagnosed about a year ago, and take 100 mg Zoloft. About 4 days ago, I had what I believe to be my first panic attack. I had ingested quite a bit of caffeine on this day, so I m guessing this is what triggered it. It was pretty scary, and lasted about an hour. Chills, discomfort in chest, tingling and numbness and this awful feeling of dread. Ever since then, I ve been experiencing what I can only describe as a lightness in my chest that goes down into my arms at times. When this happens, I feel like I m about to experience another attack, but I am able to calm myself down before it happens. I have no symptoms other than this, and no pain, but it still makes me feel uncomfortable. I would like to see a cardiologist, but unfortunately I have no insurance at the moment. Is this normal or is this something I should be concerned about?
