Danny keeps me from feeling utterly lonely, but he cannot be a boyfriend replacement. So sometimes I still feel lonely. Then I read things and it makes me feel lonelier because when I read things I want to share them with people and I have no one to share reading-sorts of things with right now.

Here is a nice sentence about loneliness:
Similarly, a beautiful concert or an unusual autumn sunset makes me feel restless if I'm by myself, wanting someone with whom to share it.

I feel this way about most things.
