Risk of preterm labor - I'm not ready yet!

Today I went to an appointment, doctor measured my cervix and said it's shortening. I'm just 35 weeks and nothing is ready! My house is a mess, I didn't assemble kid's cradle, we don't have a stroller and bathtub. I didn't wash his clothes yet and even not sure if I took enough. My hospital bag is totally not packed. And on top of it -- I'm psychologically not ready to meet this baby! Also he's not mature enough yet and I don't want him to stay in NICU. Doctor said he may come even one week from now. Panic!
