Yes, I got that same feeling when you threw down your pedigree and then copy and pasted half the DSM V into a post.
But, I've had this argument before.
There's plenty that can be "proven" here. Burnham was extremely smart. Burnham had no experience with romance before meeting Tyler. Burnham had a partial role in starting the Klingon War. These are things that can be proven because they were part of the story. We know they were part of the story because we saw it on screen.
Perhaps what you mean is, there is no way for
you to "prove" Burnham had PTSD, which is what I've been saying all along.
Burnham is not your patient. The patterns you think you see have been placed there by writers who are telling you and all of us who Burnham is, and there is no more to her than what they tell us or show us. But we are free to interpret certain things about character the way we want.
Yes, in real life perhaps you can't look for single scenes or incidents that prove a particular illness, but with a fictional story and character, many things we know and do not know about the character can be determined by a single or series of scenes. It is all up to the needs of the story and the writer's desires.
You're approaching this character as though you've had time to examine all the aspects of her life and have subjected her to psychiatric testing. You have not. There is no reason to because the show's writers are
telling us who Burnham is and who she is not.
And they did not tell us she was suffering from PTSD.
The simple answer is because the writers didn't show us Burnham suffering from PTSD. We saw definitive on screen
proof of Tyler suffering from the malady. We saw on screen proof that Dr. Culber was probably suffering from it as well in season 2. So we know that the writers have no problem conveying to us that a character has PTSD.
We see Burnham depressed and despondent only after her mutiny, subsequent conviction, sentencing, and demotion. She has no trouble functioning when she gets to Discovery.
Different writers? Different story? Different character? Reg's illness was obviously a part of his story. If the DSC writes had wanted a mental illness to be a part of Burnham's story, we would know it because it would have likely been as definitively depicted as was Reg, Tyler, and Culber's were.
Tyler has PTSD. Burnham was raised as a Klingon.
This means she had PTSD? I'm not arguing that Burnham didn't have trauma in her life, just that the writers were not telling us she had PTSD as a result of the trauma.
Burnham had trouble with personal relationships because she was raised as a Klingon. Now, you may choose to interpret this as a result of Burnham having PTSD, but if you know Trek (and I'm not saying you don't), and you know DSC (again not saying you don't), then interpreting Burnham's issues with her fellow crew members as a result of PTSD is not a given.
She didn't act irrationally when she encountered the Klingon at at the shrine. Burnham's actions after being rescued were quite logical if a bit radical. She was strident because she knew that the ship and crew were in more danger than they knew. She ran to the bridge to inform Georgiou of the Klingons. Then she sought counsel on how to deal with the Klingons from the only person she knew who had any experience with them in Sarek.
Sarek then told her essentially, that the Klingons would blow up Disco without provocation and that the Vulcans alleviated this problem by firing first. Burnham knew from her Starfleet training, which she apparently thought was inadequate for this problem, that Georgiou wouldn't agree. But because she thought it was a matter of life and death, she attacked and disabled Phillipa so she could complete her objective of saving the crew.
Seems a quite logical but radical plan, to me. Hardly irrational.
The whole PTSD thing started around here as a result of Burnham's actions in this episode. I think people (not saying you), were looking for a reason that a honorable Starfleet officer would commit a mutiny. It was easier to chalk her actions up to mental illness rather than the logical but radical actions of a Starfleet officer. So, for some, it became a given (around here and probably other parts as well), that Burnham's actions were a result of PTSD. That's how fanon gets started.
I get that you interpreted all of this differently but I think we both can agree that that doesn't make you right.
