I recently realised iam a pagan, i love nature and im very spiritual and i wish i could be more open about it.?

there is a girl in my school who is also pagan, i admire and respect her a lot because of the kind of person she is, she is just like me in almost every way but if i tell her im also pagan im afraid that she wont take me seriously or think its just a pathetic attempt to get close to her, none of my friends know im pagan either and if i were to tell them im scared they wont take me seriously. im just not the kind of person who you would expect to be of that 'hippy crowd' although i do create artwork depicting the countryside and nature. i love everyone and everything and i feel love for all nature and people and a strong interest in my heritige, truth is i have a very low opinion of myself and i just wish i could be more open- any advice would be greatly appreciated
