Great progress, and like others, I am curious why you have made up your mind that you can't compete again. In many cases, I think this is just something that is holding you back. Let's say that you tell yourself you can compete, even if you end up not competing. How do you think the results of your training will end up comparing it to if you convinced yourself you can never compete again. I think it would create a mental and physical barrier that can greatly hinder your gains, don't you think?
Train like you want it!! Train like you need it!
You're doing so well. I don't want to make this thread about me, but let me tell you, I have sustained so many injuries and illness in the last couple years, I have lost a ton of muscle. My legs have severely atrophied because some days I can't even walk due to inflammation and pain. (Getting tested for autoimmune disorders and inflammatory diseases this week. I pretty much live with pain. Regardless of how bad it gets, how small I get, how weak I get, I still get up and hit the gym and Judo. Some days I have to call it quits early though, but I am still there doing what I can and trying to hit it as hard as I can.
Anyway, I digress. Make the best of your situation. Don't let anything stop you.
