text: OK, first: "normal" vs. Lesbian.  There's nothing, IMHO, abnormal about being a lesbian, so be careful about how you use that term.  It's not "uncommon" for a woman to have a crush or fall in love with a woman such as a teacher.  Whether that's your orientation, however, depends on you and your make-up.  You say you cannot imagine "to love a man".  Why?  Are you simply not interested in men?  If you find that all of your emotional and sexual attraction is to these two women, then, yeah--you're probably a lesbian.  As for whether a woman will love you in return....love is a strange, many-faceted emotion...and you may be more loveable than you give yourself credit for here.  Be ready to have your heart-opened, perhaps broken, and re-opened again.  Peace.
