What should I do with this fear? Put it away?

Hello! I'm 13 years old and I like playing volleyball. However, my training is always on Thursdays and Fridays at a slightly later time, when it's usually already dark on the way there. I have to walk 10 minutes to the bus stop, and the bus I take takes a very strange route. The walk from the other stop is another 5 minutes. I'm very small and can hardly defend myself, and all the friends I usually go with are on skiing trips. What should I do now? The mere thought of going there alone scares me. I'm not traumatized, but the fear is still there. On top of that, my parents can't pick me up because they always go on an outing together on Thursdays. I can't use the phone either because my sister has to put my little sister to bed. What now?
