[Major spoilers for end of book]
Yes, in a way. The main character refuses to go on the mission, and another character temporarily erases his memory against his will so that he will think he made the decision to go himself. He regains his memory throughout the book.
There is a flashback scene to when the protagonist toured the facility that developed the medical robot. He sees monkeys in comas for testing purposes. He doesn't object, but states that it makes him uncomfortable, and he's scolded for being rude.
No, but it's mentioned in passing. A character realizes if their injuries were any worse, they might have received an involuntary amputation while they slept.
As much as can happen in a book. The protagonist will be in the middle of a train of thought, and it will get abruptly cut off as something else happens, sometimes dangerous.
The book starts out with the protagonist waking up from a coma and being attended by a medical robot. What follows is an especially intense/detailed/graphic version of the trope: "Hero wakes up in hospital bed and disentangles themself from medical equipment." (The medical robot only comes into play a few more times throughout the rest of the book. The only other medical scene I can think of is when a character gets their blood drawn in a flashback.)
A character enters a situation that they know will give them anxiety. They try calming affirmations as the situation approaches. They have an anxiety/panic attack. They finally manage to pull themself out of it. I felt it was handled well and with a lot of self-compassion.
Suicide is very candidly discussed in many scenes, and for some characters in the flashbacks it's presented as their best option. Detailed plans are made, but ultimately something different happens in each case.
When a character wants to describe the state of being outside the male/female binary of physical sex, he uses the word "h*rm*phr*d*te" instead of "intersex."
No sexual acts are ever "onscreen." Two characters in the flashback portion of the book start a relationship and talk about the sex they have. The TMI is played for laughs, and the most that gets shared are things like where they have sex, how intense it is, how pleasurable it is, and what they call each other in bed.
