You might be ok, but if the above posts are evidence of anything, it's that everyone reacts differently, so best to be prepared. If you really are lucid sooner than expected, that's great! But maybe don't plan on that...
The ideas for how to find an appropriate aide were good, but I want to push on the personal connections front. I think in adulthood we forget that Big Asks and the vulnerability associated with them is sometimes how we build those stronger bonds. One of my most enduring grad school friendships started with "Can you give me a ride to the far-away post office? I'll bake you cookies," to a classmate I had spoken to a handful of times. Then, when I had my wisdom teeth out, my bf was able to come down from 3hr away but it wasn't a given he would. If not, I would have asked my housemate. Or 1-2 female acquaintances (that later became good friends through other activities).
Obviously, it's still awkward...my favorite way to dispel some of the awkwardness is to lampshade it: "So, I understand this is totally weird, but this is the situation. Any chance you can help me out or know someone who can? Absolutely no pressure. Thanks for even considering it." If that doesn't seem right, maybe you could fish when in casual conversation with someone..."Yeah, so actually I'm having this weird personal problem. Can I run it by you and maybe you have some ideas? Here's the situation...I heard there are services that...Any chance you've heard of such a thing in town?" Lets you communicate "I'm looking for help" without directly putting it on them to help... but if they're moved, they might offer. Or their gym buddy/brother-in-law/etc might be out of work and could use an odd job like this.
I'd probably avoid putting it on anyone who directly reports to you (or depends on you for grades); that can get weird...not only for the student/employee who potentially takes the task, but also anyone not "chosen"/asked (favoritism?). Maybe also don't ask cute female colleagues as a guy. But other colleagues you're friendly with (esp if they are also new/single and you might return the favor?) Or using a "fishing" approach with older department admins (esp if they have lived in town for a while)?
