House-Selling Woes

So the matter of contention for the past day and a half has revolved around our house, specifically, the contract between us and the realtors. Back in June, we negotiated with a team of realtors for a whopping 6% commission. We had faith that they'd be successful. Unbeknownst to us (and one half of the realty "team"), one of our realtors decided to quit the business without notifying anyone. Right now, we have a VERY hot lead on a couple from California who need to move ASAP. They're supposed to come up from CA this weekend to view 5 properties selected by their realtor. Our remaining realtor wanted to wait to renegotiate our contract until AFTER the couple saw our house. Bret agreed with her. Unfortunately, the move made no sense to me. If the one realtor is out of the picture, why enable her to get any commission at all? Furthermore, if we renegotiate at a lower rate, that would enable us to get more money from the sale of our house (1.5% more, to be exact). For some reason I have yet to understand, Bret wouldn't call our realtor back to make the arrangements to update our contract immediately. It spawned a furious debate. Granted, I could have just as easily made the phone call, but I have something called social anxiety, and I often opt to leave phone calls from my parents unanswered, let alone talk to a virtual stranger. Call it Pavlovian, but something about feeling nauseous, having my palms sweat and my heart race is enough of a deterrent for me. You'd think after being together for 7 years, Bret would accept it by now. Obviously, my medication isn't enough for me to combat it. At any rate, I begged and pleaded with Bret to phone the realtor back and demand that we renegotiate now. He finally did, and it turns out that once again, I was right. So why wasn't the sweet taste of victory filling my mouth? Couldn't tell ya. Perhaps I was too exhausted to care. Now I'm just stressed out about these people coming to view our house. I so want to move...but we've had it listed long enough to feel discouraged at every potential buyer who we never hear from again. The stress certainly isn't helping me recover from my depressive tendencies.
