Mental health diagnosis is an ongoing process. It's not like getting a brain scan and finding a tumor. Citalopram is on of the worst with sexual side effects. Escitalopram, however, is the same basic med with the junk that causes side effects taken out (lexapro). Right now she's probably giving you a PTSD with a complex specifier as the "complex PTSD" diagnosis hasn't made it into the DSM yet.
