Some of the writers I admire who seem very very funny and very emotional to me can develop a closeness with the reader without giving too much of themselves away. Lorrie Moore comes to mind as does David Sedaris. When they write the reader thinks that they're being trusted as a friend.
Humor has bailed me out of more tight situations than I can think of. If you go with your instincts and keep your humor creativity follows. With luck success comes too.
