You're obviously quite young and these types of things happen to most of us when we first start noticing the opposite sex to any degree. If you're really keen on someone it's best to do the talking yourself otherwise unless you know the messenger very well and can trust them completely, things happen that may not be to the best.
The best thing to do now is just get on with things and treat it as a learning experience. Try not to show you're upset in front of others and act in a positive, cheerful manner.
If people see you sulking or upset they could tend to avoid you or tease you and that's something you don't want.
