I'm just sooooooo awkward!

This has literally been a problem that I have been suffering for forever!!! Okay, so a little about myself. I'm an 18 year old student studying for my A-levels and tbh everything else in my life is good, can't complain. Except for the fact I am completely socially awkward. Funnily enough this social awkwardness doesn't appear to come from a place of low self esteem. Yes, I am shy and studious, however I have been doing runway for the last two years, which has given me the unique ability to not actually appear awkward at first glance (fake it till you make it LOL). However when I start to actually talk it becomes painfully obvious that I am completely awkward :( I feel like my awkwardness is ultimately holding my back from making more friends and possibly bagging me a man! I'm 18 and never had a boyfriend. :( I just feel like I draw people in but my avoiding of eye contact, constant shuffling and quiet voice instantly puts people off :( I don't wanna change into a really LOUD person, but got any tips on how to not be sooooo awkward! Cause I think it makes people uncomfortable (especially guys). My fake it till you make it technique works on modelling but evidently not on people :) Any of my friends would say how witty and fun I am but goshhhhh does this awkward behaviour get in the way! LOL Xxx
