Girls- Can you help me? There is this girl I like and I don't know if she likes me too. Any help would be nice?

It sounds as if she likes you. The way you say she comes up to you to see if anything is wrong and how she relies on you to keep her secrets and she comes to you for lots of things as well as listens to you I would say she likes you if not just as much as you like her. I would say maybe one day when y'all are hanging out whether its at school or after just let her know how you feel. If she likes you the same then this could be a good thing for you. I wish you the best of luck :)
