Melissa Hayden should buy a Lotto ticket: This year the Guiding Light star has won both a Soap Digest award and a Daytime Emmy as outstanding younger leading actress. What's left the Pilsbury Bake-off? ''I would have entered,'' she jokes, ''but I was afraid if I won another award people would really hate me.'' Not likely. Hayden's scheming GL character, Bridget, has become more sympathetic after battling for custody of her baby son an emotional plot twist that is taking its toll on the actress. ''I get such a headache,'' she says. ''After taping, all I want to do is go home and rest.'' Hayden relaxes by watching cooking shows, because the chefs ''are so passionate about what they do. I feel the same way about acting.'' But not about cooking: ''I hate to cook!'' That's good news for bake-off contestants.
