19, female, I take singular, asthma allergies, inhalers, fluoxetine. For a few months I’ve been having feelings of blacking out and my heart will race and my chest will burn. I’ve been to the er several times for it, they gave me fluoxetine for it and it calmed down for a few months after but now it’s starting to act up again and it’s scary. I’ve seen a heart doctor and never got my results. But I’m worried it’s something severe.
