About a month ago I had a health scare and anxiety out of nowhere everyday since. Heart thumping, shaking, nerves, little sleep, starting depression. Had many med tests. Nothing appears off. Tried Celexa, bad response. Now Zoloft 25mg with Xanax to help. Wanna stick to it but side effects like increase in anxiety are hard. Positive responses and stories to encourage please. I was a very outgoing and confident person before this, having no true explanation as to why this happened makes it even harder. PS I am seeing a therapist now too...
