Yeh! I think SA is alot more serious than being shy bcuse it frustrates me wen Im shy & thought why isit that there r other shy people around & they don't seem 2 have trouble making friends, especially GF's & I or it does'nt seem 2 cum sooo easily 2me so it must b sumthing else thats wrong with me & eventually I found out, by surfing the internet on shyness'es, SA/SP, Loself-esteem or no self-esteem, no confidence. All'n'all GENERAL ANXIETY as a whole.
P.S - I also suffer Geliophobia as well. (I think thats right).
