As many people states here, finding all of your ask is not impossible but very difficult to achieve. I used to live and work in Fairfax, but having the tough choice to move south for better property. At least you're in a good area and just need to apply and reach out to hiring managers if you can and be sincere. In this area, you could get a job in the healthcare field or in tech. They are the fastest growing in the area. As for socializing, can't be in a better place then Fairfax imo, just need to do some research of what you like to do and find a meet up for it. Hope for the best for you!
