Most Helpful Girl
Why am I not worth any women's time?
Probably you are worth some gals' time you're just not interested in those gals and haven't even acknowledged them. Though in my opinion it's best suited not to concern yourself if you're worth a person's time and find worth in just being you.
"Never once in my life has a girl said anything nice to me"
Perhaps it's suited to for you to say nice things about yourself as gals aren't obligated to say nice things to you and despite what guys are often told by the media and society often tells gals don't exist to boost a guy's self-esteem/worth/confidence or ego. However if you're stuck on a gal saying something nice to you there are prostitutes/escorts you can pay to say whatever you want to you.
" I'm stuck being that debilitatingly socially awkward guy."
" I'm quite shy and that obviously works against me."
Perhaps try some public speaking courses, socializing more, and learning body language and facial expressions.
"As I sit here staring at my 9mm pistol in my hand I'm very carefully considering my last moments. "
Offnote: Does that consideration involve videotaping it?
