Am i a mezzo soprano or an alto?

i can sing from an E3 (a D slightly uncomfortably if needs be) to a G5 comfortably (but i can't belt).. which i believe is low for a mezzo soprano but high for an alto.... i can sing songs like "i dreamed a dream" and "on my own" from les miserables... "I'm not that Girl" from Wicked, most songs in the disney movies: Little Mermaid, Pocahontas, Beauty and the Beast, Mulan, Cinderella... "Send in the Clowns" and Judy Garland... things like that... im practising some songs from Miss Saigon (lea salonga as kim of course :D ) and i can sing those quite well.... sooooo.... yeah am i a mezzo or alto???
