Citalopram (Celexa) is prescribed for depression, OCD, panic, PTSD, and generalized anxiety. From what my Pdoc has told me most of the SSRI/SSNI drugs have antianxiety properties.
I hope this works for you and I am glad you have your dx worked out.
Remember the lag time on any of these med can be 4-6 weeks or even as long as 8 weeks for the full therapeutic effect.
I am so glad you woke up feeling somewhat better. I too have family that does not understand Anxiety and think I should just be able to get a "grip" when I start to feel anxious. Talking with the group here has been a blessing for me.
Stick with us.
