An excellent way to find out if you're a lesbian is to actually go on a date with a lesbian or kiss another lesbian (one that you actually like, not simply any lesbian). You will soon find out from either of these experiences if you have deeper feelings for them than just BFFs. Keep in mind again, however, that if you have been raised to think negatively of the LGBT community or simply haven't been exposed to that culture then it might seem a little awkward at first, but eventually this step will defiantly lead you to discover your true feelings. (Also keep in mind that if you don't enjoy kissing or dating one girl doesn't mean that you feel that way about the whole sex it might just be that girl that you don't like)
