i feel that way all the time. i only see "friends" now once every few months. usually i'll manage a visit by one person and then go for 3 months or more without any physical contact at all.
that's a long stretch to try to get through without passing out.
I believe that physical contact (again, not sex) is medically important as long as spiritually important. I'm not sure but I think I read somewhere on tests with people with no contact and lots of contact and people with no contact tend to grow up with a lot more problems.
