Hi Purple... My name is Chuck and I am one of the Global Moderators here on Anxiety Zone.
You are wise to be investigating anti-depressants, such as those in the SSRI classification (Celexa/Citalopram).
Benzodiazepines are a form of anti-anxiety medication that were designed for short term use, such as to treat situation anxiety. They should not be considered a form of long term treatment for more chronic anxiety conditions such as GAD or OCD. The benzodiazepines can lose their effectiveness over time, and they can also lead to physical and psychological addition.
When medication is considered to treat anxiety disorders, anti-depressants are the drug of choice. Anti-depressants actually have a slightly better track record of treating anxiety vs. depressive disorders.
I take Celexa, Purple. I have been on 20 mg for a little over 5 months now, and it has helped me tremendously. I would say that I am 90%+ improved over 5-6 months ago.
I encourage you to talk to you physician about anti-depressant therapy.
The very best to you, Purple!... Chuck
