Anxiety NWS quitting smoking, drinking

I have a patient who has had severe anxiety issues since quitting drinking a couple years ago(had been an alcoholic previously) which was significantly worsened when she recently quit smoking as well. I feel like this has to be useful info but I don't know where to look to make use of it (rubrics, etc.). Can someone point me in the right directions?

The drinking started as a social response. The patient was 13, the social group she kept were older (high school) and were drinking, so she started in order to fit in. Before she went to AA, she says she was essentially drinking all day every day for every possible reason. I'm not sure the cause of starting smoking. Of interest is that she never had any problems with anxiety over public speaking before this. When she quit drinking it began to develop, and since she quit smoking a month ago (for the second time) she has terror at even the idea of getting up in front of an audience. Her anxiety also manifests in suden panic attacks where she fears to pass out in front of other people, has to find a bathroom or similar enclosed space to get into. When I asked her if it was the open space or the people that was the worst factor she responded that it was the people.

Got it. Will hopefully be getting a clearer Hx/timeline from her soon, will have better ideas. Thanks.
