Welcome to the RQT club - yes, you have sustained a very serious injury, with a long rehab sessons in front of you.
I am attaching a set of documents which explains your injury and the rehab process - the documents cover a Ruptured Patella Tendon, but the rehab is very similar.
The key word is PATIENCE - DON`T PUSH it - read previous posts and my documents with care.
Keep posting - and a pillow between the knees is the best method of getting a decent nights sleep, and I am doing this even after nine years.
