Working with numbers/degrees of difference helps me. I tend to push away one or two people and decide I push away everyone when that's not true? So I count :-) and make sure I talk to 1 in 3-4 people, say; or, make sure I talk to at least one person a day (doesn't matter if it's just a store clerk). That keeps me on a more even keel and not quite as isolated feeling. I tested it out though and radio/TV or the like didn't work at all, has to be real people.
