i like my best friend ig?

sooo...
i think i like my best friend
and i hate it so much
ik i dont even have a chance with her
shes straight, like seriously straight
and ive been questioning for two years, i think im bi
shes really touchy with everyone, and its kinda her thing to randomly sit in your lap or draw circles on your thigh through your tights and stuff like that
and everyone is fine with it but i get seriously nervous when she touches me
sometimes she'll be sitting in class and i'll look at her and... ugh i hate this
its not really a question i expect to be answered but
does anyone know what to do or anything <3
