I am this guy and I mostly mitigated it by being active in a bunch of different circles. I'm known amongst my friends as the guy that has way too many hobbies. That said when I'm alone I almost invariably play fighting games or narrative driven games (and the occasional rogue lite such as vampire survivors, ball x pit, monster train, slay the spire, etc) . I'm an insomniac and often am up twenty hours a day. I took up dancing 3 nights a week as a way to be social and stay healthy.
