I have been struggling with anxiety in public settings for about 6 months and it was getting worse and worse. I went to see my Dr and she put me on Lexapro 10mg per day and I started it on Saturday. Felt fine the first two days and then on day 3 I had a panic attack in the evening and then a horrific one in the middle of the night. Since then I have felt anxious and my Dr prescribed Xanax to help with that and says that it will get better just have to keep up with the meds. I keep feeling like I'll never feel normal again. The Xanax does calm me somewhat but I can't take that forever. I've missed two very important days of work and it's looking like tomorrow will be the same. How do you know if your on the wrong medication or if it really needs more time to work??
