I have a good friend with a psychotic illness, and yup, secretive and resistant to change about covers it. Is she receiving treatment and taking her meds? For how long? My experience is that my friend gets back to 'her old self' (more resilient, social, easier time changing and talking) after about a year of being on her meds as prescribed, with manageable stress. It seems to take that long for her brain to sort itself out again.
