MTM82 - I came to the exact same realization when my outpatient treatment program insisted that I see a psychologist who referred me to a psychiatrist. There was nothing scary about the process, contrary to what I had built up in my mind as an excuse for not getting help in the past.
I sincerely believe that the majority of us are self medicating underlying anxiety/depression with alcohol and other drugs. Remove the anxiety/depression, and the compulsion to use is lifted. Congratulations!
FYI - when you come off of the citalopram, make sure you wean off under doctor supervision. The withdrawals can be nasty. All I will say is "brain zaps." Check it out.
