OK if I were in your shoes i would probably go SM7, set flat, into a UA 610 cranked, into an LA-2A cranked. Comp enough takes for not only the one vocal track but also a doubling track, which you lowpass to remove annoying consonants and process differently and mix lower. Correct pitch, tasteful EQ/verb/delay, and bury in the mix by not making any space for the vocal. Consider doubling with another subliminal instrument like a synth pad or something to sweeten it if it's really awful.
BTW don't feel so bad about your voice if this is really for you.
