what can you do if you think you look 'different' or 'odd'

i've had a complex about this all my adult life, about how i look, my appearance....ive never been that confident in myself......i'm now bald, have a moustache, have olive skin, blue eyes but its not just that, i have a complex that my look or features don't look right?

i do see people observing me in public at times and it unnerves me...i feel that there's something not right with how i look...my elderly mum and dad say i look ok that i look just average and you wouldn't pick me out in a crowd....but inwardly i'm not convinced..

anyway, what can you do if you think you look different to most people or look distinct? how can i carry myself when i go out...i have severe anxiety i live with as well.
