Take some time off if you can. Seems like they didn't put your picture up cause they wanted the other person as the lead. Like a way to push you out. You can apply elsewhere, you can report the issue to higher ups.

Glad your wearing something for your poor feet. Vionics are orthopedic shoes, those might help you. My former chiropractor boss sells them. they have a website. Good shoes are a must if your on your feet.
