I know what you mean, I too work basically alone except for phone contact. My best friend that I had known since 2nd grade passed away this summer (after a long battle with brain cancer) 3 days after my wife dropped the bomb(I think she wanted to get her bad news in before he died) I do have other friends and we go out at least once a week and raise hell which is the only thing that keeps me sane. You may need a weekend trip solo to visit some old friends or family just to keep your sanity.
