Pelvic i know precisely how you feel.
i have recently gotten a lot of my confidence back and will occasionally wear heels BUT i do (until i get a bit tipsy) still feel as though everyone is staring at me and i feel like a big freaky tall person.
and without causing offence, it is easy for people who are 5'8-5'10 saying "i like being tall" " don't let it bother you" "there are loads of tall women" because they are tall for women
we are tall in every catagory. i go to a bar and i am head and shoulders taller than EVERYONE in there.
men will usually say "oh i like a tall girl" but being my size isn't at all feminine looking and is usually very intimidating to men (pathetic as i know that is)
So don't beat yourself up for not feeling comfortable in heels Pelvic.
not to mention its almost bloody impossible findig them for a size 9/10 which i am
