Baveleee Hello, I understand your worries and anxiety. Judging from the problems you described, her problems are indeed symptoms of phobia, but the real cause of the fear is not the fear of new houses; Fear of oneself, this symptom of insecurity has nothing to do with academic qualifications or career.
I don’t know if your wife has had similar symptoms before. What has happened to her recently? How long has this situation lasted? If it has a serious impact on her work and life, then if conditions permit, it is best to take her to a psychological counseling center to release her inner fear and repressed fear. Her fear stems from the lack of security. As long as Once her suppressed emotions are released and her inner worries are identified, she can naturally return to her previous state.
If she is unwilling to come for counseling, you can ask yourself to post questions online, and there will be many professional counselors here to guide her. So please don't worry either way.
Best wishes!
