i think it is possible to become dependent on ativan. i was on it for a while and definitely felt a little worse for the wear coming off of it. it might help to start the Effexor and as it begins working, gradually come off the ativan. once the Effexor really begins to work you wont need the ativan in the same way.
i'm glad to see you. . . i was wondering where you'd been.
hope youre feeling better soon. and yes, therapy definitely helps but whether or not its enough on its own depends on the person.
