I am doing my best to stay caught up, so forgive me if this has already been addressed.
Regarding OCD & being under the care of a psychiatrist:
I've struggled with anxiety & panic attacks for 15 years. In February, I was hospitalized for mental health treatment. I was then diagnosed with OCD and put in the care of a psychiatrist upon my release. The psychiatrist made it very clear that my right to confidentiality ended if I was a threat to myself or others. Unless BL was a future threat to someone or himself, his psychiatrist would stay quiet about anything he is sharing.
Additionally, I was able to make adjustments to my medications with my psychiatrist over the phone, even when I was newly released from the hospital, even across state lines (we are military.) IMO, I don't see the need for him to fly back to either address meds or have a conversation with his doctor, unless he was being hospitalized.
Regarding OCD specifically: Generally speaking, most people do not have a clear understanding of OCD. It is not uncommon for people to go 10+years after onset of symptoms to get a proper diagnosis because people don't recognize their symptoms as being OCD. It is also not uncommon for people to say they have OCD because they are organized/particular about things. That is NOT OCD.
In the body cam footage, GP says she has OCD "sometimes." That really stood out to me as being something odd for a person with an OCD diagnosis to say. It's not for me say whether or not she has OCD, but I can say that they way she referred to it struck me as VERY odd. It would also surprise me that she was diagnosed with OCD by 22. Symptoms typically show up around 19 years old. It's not impossible, but definitely not typical. It is also VERY hard for someone with OCD to be away from home for extended periods of time. This could either point to her not having it OR could explain why she seemed to be struggling so much in that footage.
