Torn ACL injury ????????? - how long does an acl injury take to heal

I am 13 years old and I think I tore my ACL playing football in my school. How do I know if a cruciate ligament, and how long would it take to heal, if it was. My symptoms are that I do not limp when walking can to bend the knee without pain when sitting or basket, which will not be easy.
