First, you need to find someone to talk to. It can be a professional therapist where you can work on your mental health and how to better cope through the tough times you are having, or just some close friends where you can communicate and feel like part of a community again. Talking to others and having constructive conversations not just complaining about everything you hate and being a huge bummer will improve your entire demeanor.
Second, you need to find something fun to do everyday in addition to running. There is more to life than work and running, find what drives you. Spend 30 minutes a day doing something you enjoy or trying something new to see if you could like doing that. I can assume up to this point in your life you have been busy with school, running/running competitions, and the social life that comes with both of those activities. Early adulthood, especially when you move away from your safety net of friends and family is the first time in your life where you alone are in control of your happiness. If you can figure out how to be happy where you are, when you are able to find a job in a better location you will be better equipped to be happy there too. If you don't do this now, a change of location won't solve all your problems.
Third, figure out how to be really good at your job. You currently have very limited distractions in life. Take advantage of it and figure out how to excel at your job. Spend at least a year there and you should be very easily able to make a lateral move to a more desirable location.
Fourth, if there isn't a running club already where you are, start one. Everyone should be welcome regardless of skill level. If you can get people to join, set up a race for later in the summer. Maybe the local town has a celebration for the solstice and suggest adding a 5k or mile fun run under the midnight sun? Get creative if your community is socially distancing. The gyms are closed so people will be looking for an outlet to workout.
Just make the best of your current situation. It isn't ideal, but life never is.
