Find a primary and differential diagnosis with justification for this case study || 100-200 words Case Description: Zula Zula is 42 and lives with husband, Henri. Her younger sister lives on the same street. She has a daughter aged 12 and a son aged 7. Zula has not worked since her part-time contract payroll officer job was completed about 2 years ago. Although having a mildly unhealthy body weight, her general health is good. She is not currently taking any medication, her alcohol intake is within social norms, and she has never abused substances. Zula presented to your service today after an urgent request for an appointment. She said that she had been involved in a motor car accident two weeks ago and had been "pretty wobbly" since. “It shocked me. I was very scared ... Henri was driving me to the hairdresser and a truck backed out of a driveway and we ran into the side of it. I feel so bad about it... he really didn't want to take me ... he had a big meeting to go to, and he was late and upset and angry. I know it's silly but I feel like it's my fault that our car is a write-off... and what would have happened if the kids had been in the car? Oh it was awful! Awful! You know, I can't bear to walk past the garage now, because I picture the poor car smashed up ... the bonnet bending up high and blocking out the truck, the horrible crunch ... and then there was dust floating around inside the car! I try not to think about it... I just put it out of my mind and then I don't think about it unless I walk past the garage or someone asks me about it". She said that the precipitant for her coming to the appointment was that “I can't go to the shops anymore”. On questioning, she agreed that since the accident she was anxious about travelling in a car ("I've been jittery about the traffic”), but she seemed more concerned that "I can't go to the shops anymore because our car is gone and my sister starts a job on Monday". She said that her sister drives her to the shops every Wednesday, "It's been a regular thing ... since my daughter's 11th birthday, actually. And Henri helps with the Saturday shopping. They really are good to me". On questioning she said that she has a drivers licence but rarely drives, "I'm not a confident person ... I prefer to stay at home ... I'm always jittery about something going wrong when I'm out”. This seemed to refer primarily to places like large shopping malls and the city centre that she saw as “….. huge and full of people” “... and I really can't stand waiting in the queue at the post office, too”. When asked what might go wrong, her face flushed and she said in a quiet voice, “I'm worried I might, you know, have an accident". [Q: What sort of accident?], "Well when I'm at Epping Plaza Shops, I start thinking about what if I didn't get to the Ladies in time”. She described the fear as “... popping in and out of ... my mind before I leave home", and getting worse once she was out. On a bad day, it is clearly intrusive and intense, accompanied by clamping of her teeth, noticing tense neck muscles and faster breathing, and sometimes noticing she is flushed and sweating. She said she realised that “….. something bad probably won't happen but it might ….. and if I'm at the Plaza by myself I can't stand it, and I get out of there as quick as I can. Even when I'm with my sister or Henri I'm always keeping track of the door to the car park. And I know exactly where all the toilets are ...". She looked surprised when asked if she also feared at those times that she might lose control or go crazy, saying she had “... never thought those things”, though she added that recently she has more often worried she might faint than be incontinent, “... but it's usually OK if I've got my support team [Henri or sister]!”. ... ... Further queries established that she had not had any episode of incontinence, and did not worry it would happen when she was at home, or when she recently visited her old school friend nearby. She reported that when she was with trusted others she would go to the city or even a concert, “. because they are very good to me they'd help me”. Additional enquiry established that when she was employed she drove herself to work several kilometres away, and only saw her sister every 2 or 3 weeks. She agreed that "... things have slipped" since she finished work, that she had been unsuccessful in the only 2 jobs she applied for since. Although Henri was pressuring her to get work, she was putting it off "... for a bit longer till I feel up to it". This seemed to relate not only to her current distress about the accident but to her ongoing lack of confidence.
