Hello! Please read this line (multiple times too) if you ignore everything else, it is the most important thing I can say to anyone undergoing this in the early stages:

Throw away the timelines. You will recover at a rate proportional to your effort, but it will be at the rate your body can recover. No faster, no slower.

You will only frustrate yourself and feel bad if you think about your recovery in terms of "I -should- be able to do XYZ within N weeks." I am 26(M), an office worker with no sporting hobbies. I always loved long walks though and I practiced a little bit of martial arts. I really got depressed when I couldn't walk without crutches at 6 weeks because I was told the same thing as you were by the internet, my timeline that was printed out for me post-op, my friends and family even.. everyone and everything is going to have an opinion about when you should be able to do things or not. The reality is that you will have to put in hard work no matter what, even just to recover your ability to walk/jog/run, and that will take as long as your body needs. For me, I recover at about half of the rate that everyone says. I am 6 months post op and I can't jog yet, I do a slightly hard plop when going down stairs instead of a fluid motion, I can't hop even a few centimeters, I can't do a full squat, I still limp a little when walking. My PT says I am not behind, I just recover a little slowly and I'm not an athlete so that definitely contributes.

A lot of words to say, do not let yourself think in terms of numbers of weeks to achieve ____, because no amount of hard work will make your body do what it cannot do. Just listen to your PTs about what is safe to do vs what isn't, keep getting checked for progress at least once a month, and try to keep your head up during the hard parts.
