I don't see anything wrong with having only a handful of friends. However, the "find my future partner online and have the rest work itself out" seems pretty speculative. You might find volunteer work a way to ease into a more social way of life. This would not have to be full-on social. Food banks and community kitchens also need people to pick up supplies, wash dishes, and sweep floors.
