I have been feeling nauseous and also yesterday I almost passed out. Usually when that happens I lie down and the dizziness goes away, but it took awhile for the feeling to leave. I have also been having these moments throughout the day where I get shortness of breathe and sometimes it is so hard to just breathe. I do have anxiety and depression and about two weeks ago stopped taking my medication which was Zoloft because I felt like it wasn t helping much and was prescribed a new medication(lexapro) and I took it and had a hard time breathing and had this horrible feeling like I was going to die so I decided to wait a few days and I m not sure I should start it because I feel the same symptoms I did when taking it. What should I do and what is wrong with me?
