Hmmm your wedding is supposed to be fun and all about you.
If it's making you stressed out and crazy maybe you need to sit down and re-evaluate what you want.

How about enrolling your Mum, your sister and/or your bestie for ideas, motivation and help.

I saw a TV program once about a couple that had an ebay wedding - now I'm sure you don't want to be that cheap but there are lots of second hand dresses out there that are only worn once.

Maybe a couple of bridal magazines might help you but their main function is to sell the really expensive products that are advertised in there so you need to take inspiration from there but not use it as a guide IYKWIM.

What about wedding expos - once again to suck you into spending money but lots of stalls have freebies and competitions so if you go you might get inspiration and win something.

If it all gets too much jump on a plane and go to Vegas - that was my dream wedding.

You could hire a wedding planner...
