And hang in there @HopefulSocPhD I can very much relate. I'm also a teacher and an older applicant. In fact, at 40, I'm more of an outlier. Although I have some research experience from undergrad and grad studies, none of it is directly related to the type of research I'd like to pursue in a sociology phd program (my recommenders were anthropology and poli sci professors). I'm also transgender and my proposed project relates to the emergence of the transgender rights movement so my research agenda isn't a "great fit" with too many departments out there. In other words, I'm not an easy sell. But even though this application round has been soul-crushing thus far, I'm not giving up. As per the helpful advice of many of you, I'll look for research positions for the coming year, revise my writing sample, start contacting professors whose work interests me, and maybe even try to publish a paper or two (though first I have to write something of publishable quality!)
Hugs to all my fellow applicants who have seen nothing but rejections thus far. We'll be ok!
