I Told her... Ooops.?

So I finally had the guts to tell my best friend i been in love with her for a while, she said she loved me, but now in that way... When she said that i felt like my stomach dropped.. Now I feel like it's awkward.. Considering i'm a girl and she's a girl... We haven't talked since that day.. I text her but it seems like when she text's back she doesn't wanna talk to me.. I really have no idea what to do... She told me we would still be best friends, but i felt like she was lying ... I have no idea what to do, i don't want things to be like this.. should i tell i was joking or what. She's my best friend and i don't wanna loose her for something that i said.. What should i do?
