I haven't been through quite what you're describing, but I do feel your pain and have been where you are now. My sister was in a near fatal crash years ago. She passed out at the wheel out from lack of insulin in her system and wrapped her truck around a huge tree. Shattered most everything on her left side from the impact, but she is virtually recovered from it all aside from some mildly chronic pain, and joint soreness occasionally. But seeing her badly beat up in ICU with pins, cables, weights keeping her leg in alignment really tore me down. I have trouble even being in a hospital, much less seeing someone I know and love in that condition. Its definitely a good thing he is keeping a positive state about it all, but to him its not over with. There will be tons of rehab work for him to get frustrated about so hopefully he keeps a good attitude through it all. I wouldn't take the first diagnosis as prophecy just yet, doctors can be wrong like anyone else so there's hope that he can still lead a normal life. Good for you staying strong, somebody has to and you've taken it upon yourself to be the one. Just maintain in front of everyone as much as you can, but be sure to give yourself some time alone to help cope and crack down a little......its not a bad thing that you need to grieve about this, human nature man......dont think you're less of a man because of it, I dont even know you but I can tell you're being a big man about it all. Best of luck to you and yours, I truly hope your bro pulls through this to ride again!
