At least a few of the programs you ranked from 1 through 7 most likely required your family to move from your current home. No metro region has seven derm programs, except Chicago, which comes close with six.
Therefore, I would hazard that your unhappiness with your match is actually based on your perception that it is not as prestigious as the seven you ranked ahead of it:

I am going to weigh the pro and cons of moving my family from this program. Another reason I don't like the program is it is not well recognized and I want to enter academics later. The other schools lower on my list were not as good either in my opinion.
As a medical student, you are in no position judge the qualities of a residency program based on a superficial day-long visit. Certainly, you are not a dermatologist, and it is the height of arrogance that you would consider your judgment of "good" and "bad" programs to have any real validity.
Feeling that you deserve to be happy because you've worked so hard (see previous link for quote) probably stems from your sense that you deserved to be at a "better" program, when in reality ALL derm programs are highly competitive. Digging deeper, I wouldn't be surprised that you wanted dermatology because it's perceived as prestigious, and you wanted a "good" program because you also wanted the prestige that comes with that.
If your claimed academic interest in skin was real, you would currently be grateful for matching at all, since any program can fulfill your stated desire to enter academics. I highly doubt none of your faculty members are publishing. Even if they aren't, you can undertake case reports, case series, and clinical studies on your initiative if you ask for their support.
None of your declarations, of course, really have anything to do with your claimed deep-seated academic interest in skin, because if they did, you wouldn't even consider an anesthesiology residency. And really, why anesthesiology and not, say, family medicine? If you went into family medicine, or even internal medicine, you'd get one-thousand-times more exposure to skin than in anesthesiology. Prestigious family medicine programs would be falling all over themselves to have you as a resident.
I'd hazard to guess that your flirtation with anesthesiology is based on the fact that it's part of the ROAD, and on balance, you want the money and prestige that comes with being in the company of radiologists, ophthalmologists, and dermatologists.
Many, many people would have loved your spot -- would have loved to interview, and would have loved to match. Your ingratitude is galling.
