so much to do; freaking out

okay, so i'm the first one of my friends to get married, my older sister is single and i was 10 when my brother got married (and it was a very low key wedding) so as teh big day gets closer, i wonder more and more what i am missing. i'm sure i have thought of all the major things but i read these threads and i start freaking out... what is a gable box? slipper basket? aaahhh. i haven't really stressed at all until now but all of a sudden - i see why weddings are so stressful! so tell me girls, what are the 'little' things that i'm not thinking of? i need to make a list!

i have done:
- church
- reception hall
- dj
- photgrapher/videographer
- my dress
- the girls dresses
- picked out the flower girl dress (we're going to get her fitted in july)
- ordered and received the invitations/have a calligrapher
- booked a honeymoon
- have most of the guest list finalized
- have a hair girl and a makeup girl booked (run-throughs won't be til sept probably)
- picked a florist (but they said we don't have to meet with them until 3 months before or so)
- cake (my reception hall does it, though i haven't figured out what i want)
- favors (reception hall taking care of it)

i know i need to do:
- find a dress alterations place
- engagement photos
- bridal party gifts
- veil
- shoes
- tuxes
- wedding rings

so, what am i missing? maybe nothing and i am just freaking out because i can't decide on the cake or the flowers or the songs or photos for the montage or readings at the ceremony.
but i am questionning things like the menus... doesn't the reception hall do them? and the centerpieces - do i have to buy anything for them?
so if you couldn't tell, i am freaking out! 06 brides, help! particularly, october brides

I think you are doing really good!!!! don't stress....you have a lot of the big stuff done! some little things to add to your list (some optional, but i thought i would add them)
-undergarments
-RB pillow/FG basket
-programs
-rehearsal dinner
-guest book/menus/placecards
-?transportation/limos
-day of jewelry
-register

Just wanted to say Welcome and good Luck! Dont stress, all will work out!

thanks girls! i actually do have my undergarments and we are registered and we're not doing programs because the bridal party is so small. flower girl basket and guest book i will definitely add to my list. anything else?
oh, and i'm actually not having a ringbearer... so what do i do? does the best maid and maid of honor just hold the rings then?
