Where is this money coming from?

We were just going over how much money we have to have for all the vendors (w/o envelopes, favors, BP/GM gifts!) and w/o the final payment to the hall. I don't know where we are getting this money. We absolutely are running out I feel like throwing up I am so stressed I can't deal. This is so upsetting. And we need to start to look for an apartment! Which will be money once we get it. What do we do ? FH and I both make good money (him more than I ) we are very comfortable. This damn wedding is costing out the butt! I just want it to end already
