I you tore a ligament, perhaps the medial collateral (MCL), indeed it will not heal. You knee will get to feeling better but will be "loose" unless surgically repaired. This is major surgery, not athroscopic. My daughter had an ACL reconstruction with meniscus damage. It wasn't pretty. Rehab is long and tough and her knees still bother her on runs. She has not been able to attempt the Marine PFT. She's still doing therapy on it.

Generally, it takes an MRI to be reasonably certain of the diagnosis, and this doesn't often show meniscus damage. X-rays often don't show much detail on soft tissue.

Indeed, you seriously need to follow doctor's reccos and ensure you are seeing an orthopedic surgeon or sports medicene specialist. This can be more than just a month or two out of high school - it can impact the rest of your life.
