I wish you the best of luck!
Remember when that used to be called 'being shy'?
It's insensitive/cruel to mock someone's diagnosis when you know next to nothing about the details.
There are larger arguments about overdiagnosis in the US, etc., which is all interesting, but if you're talking to an individual about painful experiences in their past, bear in mind that generalities cannot become rules.
Social anxiety is a very debilitating and tortuous thing, as is any form of chronic anxiety.
I hear you are stressed out by dealing with the resulting success of your game and are willing to shutter it to save your sanity. I also hear you want someone to 'take you seriously' in making an offer for the game. Those two statements, if I am hearing you correctly, are in direct logical conflict with each other and may lead to causing you more suffering. The technical term is cognitive dissonance, literally believing two things at once. In your case you appear to hold the opinion that the game is worth something and you must be paid for it to release it, yet you thinking about continuing to manage it will lead to a loss of sanity. Resolving this logical dilemma sounds impossible, unless someone pays you a lot of money or you really intend to shutter it.
I would suggest that if you intended to shutter it because of suffering reasons, you would have already done so by now. That may be related to the fact those-who-create live to do so. I am one of those people! If that is the case, you must face the fear of continuing the game's existence.
Attempting to face a fear you are capable of facing will help move you forward past this event. Perhaps Open Source it, or take the other suggestions offered in the thread. I appreciate the fact you took the time to tell us about it. Creating brings joy.
Remember, your suffering is your choice. Only you can reduce it. Only you can wake up in the morning and be grateful you are here in this reality and then attempt to reduce your suffering by facing your fears for the day. Nobody else will do this for you as we're all trying to do it for ourselves each day. Best of luck to you, my friend; today is the first day of the rest of your life!
Please don't kill yourself over a game. Release it AGPL and be done if you have to.
OP, you probably see Klinic every day on your way to school. They have trained counselors 24/7 at:

Your graph reminded me of a scene from The Simpsons where 'Disco Stu' presents a graph entitled "Sales of Disco Records, 1976-1977" showing a massive upward swing. Seeking investment for his idea, Stu indicates "If these trends continue... aaayyyy!"
Not trying to talk you down at all - but if this level of interest is unwelcome to you, the chances are good that it will get better. Most things run out of momentum pretty quickly if you're not actively keeping the ball bouncing.
I read in your article that you offer a bit of support. If you manage get to make a deal with someone, do make sure that in your agreement you explicitly mention for how long you will offer support. Make it nice and short, like 3-6 months, perhaps just a few weeks.
If you are tired now, you will only become more tired if your support of the project goes on, and it will keep worrying you if there's always someone who contacts you about things of your project.
If the amount offered justifies it, perhaps find out if your university can get you in touch with a nice contract lawyer that can go over the transaction for you, but don't worry about it too much. There's not that much can go wrong, as long as the agreement is clear that everything is supplied 'as is' and the support is properly time-constrained and makes no promises beyond 'best effort', and especially if the other party is allowed to inspect the goods before receiving them, not much can go wrong.
If you are the worrying type, you could put the funds received in a savings account and not touch them for a year or so, so you'll always have funds to settle any disagreement.
I guess keeping it "as is", without any support, is better than shutting it down, but I don't know if I could simply ignore it.
I would try it before (if) shutting down, though.
Ideally, if you put up a graph of your costs per month (including what you feel you should get paid to work on the project) and a graph of donations per month, or something, then people who enjoy your game will be smart enough to help support it financially for you.
If you do decide to shutter the server, set up a Github repo and mirror your code under a licence like GPL3, then maybe at least someone else can pick it up and keep sharing more cool stuff with it. It's what I did when I got out of roleplaying games.
When I was a student I had totally-free online stuff I built lead to a stream of requests for upgrades, additions, bugfixes, etc. -- and the unreasonable ones are easy to discard, but some requests would be polite, friendly, and include offers to help. I'd agree to make the seemingly-small tweak, or accept the help, and then realize after a week that I didn't really have the time, or that my TO-DO list was being pulled completely out of whack....
Better to not publish your email address at all, perhaps, or make very clear that emails may be eventually read but very likely not responded to.
Besides, most of them are probably just writing to tell you how much they like it, or wanting you to partner with them.
You don't have to answer any of them. Just put up an autoresponder explaining that this is a free game and you're a university student and can't respond to email.
I mean, this is what Google does and many/most people love Google products.
(I know some with social anxiety, and it sucks that society is so dysfunctional that we don't make simple accommodations which help us all realize our potentials. Hope all goes well for you.)
If you ever start to feel down or like life is not worth living, email me - address in my profile. I'll try to do what I can to help.
Some people don't think only on money. I created this game as a fun project, for fun, without expecting any revenue. (If I did, it would be pay-to-win).
I tried to kill myself last year a few days after I gave a talk at a FOSS conference. Some people can't handle pressure, email volume or too much social contact, specially if they have something called social anxiety, depression, and other things that I do.
I understand your suspicious.. However you are assuming I'm a crazy-for-money guy like... many people.
If no one buys the game I'll probably shut it down. For my own mental sanity.
