Seem to me the anxiety and depression sound like bigger issues than the thong fetish. I'd suggest seeing a therapist that works with patients with depression, most of them also can deal with sexual disorders. Sounds like you know this already but antidepressants are notorious libido killers, can cause ED and inability to ejaculate.

Best to you.
