I would tend to agree with your psychiatrist, who suggested that feeling as though you’re living in two worlds may be a coping mechanism. It’s also possible that the two-worlds feeling is a symptom of psychosis.
Other explanations include your disassociation is to blame or it may be that your medications are interacting in a negative way. Being on the wrong medication could also be part of the problem.
Unfortunately, it’s impossible for me to make a determination about what might be wrong without having the ability to interview you in person. I would suggest attempting to find a mental health professional whom you trust and feel to be competent. This is not to suggest that your current providers are incompetent but perhaps you haven’t found the right treatment providers for your needs.
Understandably, it’s difficult to make these inquiries while continuing to experience intrusive symptoms, but it’s worthwhile to search for professionals who can meet your needs.
You might try dialectical behavioral treatment (DBT). DBT is a specific type of intensive therapy that targets many of the symptoms described. Some of the concepts for DBT were derived from Buddhists meditative practices. Studies have found that DBT can be quite effective. I hope this helps. Please take care.
