How do I become friends with het agian cuz I like her nd I am a girl

I am a girl who is 13 nd I like
another girl
nd we were best friends until the day I told her that
i had a Huge Crush on her then she
said she was uncomforble wjat do I do
cuz we r also in the same class nd
she ignores my meessages

Unfortunately, I think the only real solution is to give her time. Tell her you're sorry for making her uncomfortable and that you hope you can still be good friends, and if she acts weird don't trip! Use this time to get closer with your other friends while waiting for her to come around but don't stop being friendly to her (but don't seem TOO friendly, or she may think that you are still coming on).
Hope this helps at all :p
