thanks everyone! i really do appreciate the advice - even from those few of you who came across as a bit judgmental.

i probably would be thinking the same thing - how can you do a disney vacation when you are afraid of losing your home!?!?! trust me, i get it and can't truly justify it except to say the disney trip is costing us nothing but food and since we are sharing a dvc with our friends, we can eat in more often than not. (we were going to cancel it but our bff's bought our airline tickets for us because they didn't want to go without us, we have left over passes from our last trip that we will use, the kids go for free, dd will share our meals, we won't need a car rental, etc.) we already know we won't be buying any extras during the trip - it will be the cheapest disney experience we've ever had.
we are both working full time and dh actually has a 2nd part time job as well that he took on when all of this began.
we both have work issued cells - we dropped our personal cells already. we have the basic cable package no movie channels, dvr, hd or anything like that.
we stopped our trash pickup ($40/month), carwash ($26/month), we've never had lawn and snow service, etc.
i have made 2 changes to increase my paycheck by claiming 1 instead 0 on my W-4 and i used to purchase an extra week of vacation for 2% of my salary and dropped that as well. (the vacation purchase change won't take effect immediately but it's in my near future.)
i think we have 3 things that have really put us over the edge...
1. we now have our dd in daycare 2 days a week. my father used to watch her for us but can only watch 1 of the kids and the baby is easier for him and would cost more for daycare. we don't have anyone else that can/will watch her for us when we work and we have modified our schedules as much as we can to only place her 2x a week. we also use the daycare at dh's work so we get a discount there too.
2. i had to have emergency dental work that wasn't covered by our insurance and that cost us quite a bit of money that we weren't ready for. i actually haven't finished that process because we can't afford the rest of it right now - hopefully i won't end up losing my tooth.
3. thnot exactly sure how it went down but basically dh either got bad advice or (more likely) misunderstood the advice given to him by a rep at our mortgage company. ultimately he ended up "missing" a mortgage payment because he thought he was told that would make them work with him to lower our monthly rate. (makes no sense to me but i wasn't involved at this point.) when he called after the "missed" payment it was an entirely different story than he had thought and they put us onto a repayment plan that is completely beyond what we can afford - about an extra $1000 per month! if we can manage to make the payments and get this taken care of, we should be back to normal payments and a far more managable money situation come feb. we just have to get by until then.
