I’m curious what kind of human contact you’ve “tried” that didn’t work. There’s a world of difference between contact that is mediated through the context of work or planned leisure activities with relative strangers and organic meaningful interaction. Humans need to be social and feel useful to those around them. If that is lacking in your life, I suggest volunteering somewhere. Your local humane society almost certainly needs volunteers who can wash dogs and cats, or help visitors interact with the animals. Or there are likely a number of places you can volunteer to help people who are hungry or unhoused.
