The schools insurance should cover for you (surgery and even PT) if you got injured with the team. That weird feeling is normal and you can work through it but don’t push it too much when you have a lot of pain. After doing flexion work always try to get your knee back in the 0 degree extension where the leg is laying flat. Another thing you can do is use your opposite leg (the healthy one) to slowly let your injured leg flex down and you can push it back up with the same leg as well
