I have had moderate depression for the last year combined with mild anxiety. I finally saw my GP in September and addressed these concerns with her. She prescribed me Celexa and Xanax. I filled both, but ultimately only took the Xanax (as needed) and held off on the Celexa due to the side effects and hoping my depression would improve on its own. However, events have happened in recent days that have caused my depressed to go from moderate to severe (with suicidal thoughts). Should I go ahead and start taking the Celexa or go back to my GP and ask for something that may be more effective for severe depression? At the time of my visit with her my depression was only moderate. Thanks in advance.
