I wouldn't give up hope yet--rejections/admissions are really weird and don't seem to really follow much logic (as I'm sure people here would agree with!). I was in the same boat earlier and then got into Cornell. Actually was googling "got rejected from all PhD programs" and a lot of good articles popped up--most suggested finishing strong at current job/program for good LORs, finding something that interested you, and remembering that any potential rejections are not a reflection of your worth. Good luck!
