When I was inpatient as a teenager, I had the terrible experience of staff going through my journals and laughing. I have since only kept notes that are either too cryptic for others to understand or anything really revealing gets written down , talked about in therapy then the page gets torn out and tossed. I am especially nervous about carrying the notebook on me at work. Because at work, I use similar notebooks all the time for meetings ( if I don't know someone I'll jot down his or her role and ask someone later that kind of thing)
