I'm 14 and have severe anixety and depression, iv had derealization for a 5 months. every thing seems so unreal, my vision is all different, I feel like I'm dreaming all the time. my doctor described me celexa 10mg, and I'm so terrified that it will make the derealization/depersonalization worse or not help at all. I'm so scared to take this medication, I can't deal with this feeling being any worse then it already is, I can't even go out to the store with out having a panic attack. please help
