New to ug but not to working out and need some tips

Ok this is gonna be a long story, but here we go. A few years ago, I was in my last semester of college about to graduate from UF, until I came down with bacterial meningitis from “swimming in dirty water,”I was told. However the only dirty water I was ever around was the sewage overflows in my crappy apartment that I made multiple complaints about to the office that were unanswered. I even went to the hospital and they started giving me an x ray which had nothing to do with what I was complaining about! So of course, they stereotyped me as a typical college kid partying and doing drugs and told me it was a flu. I knew it wasn’t and was something worse and asked them if they would just do their job and check my white blood cells count for an infection, but they insisted that they already did everything they could and just prescribed me some ambien for sleeping (one of my complaints among other classic bacterial meningitis symptoms like stiff neck, etc) and then I said “alright I’ll see you guys in a few weeks.” I had hoped I was just kidding, but boy was I wrong. One night after getting home from the gym, I went to make a protein shake, but I bumped into the button to turn on the stove it was sitting on, and the next thing I know is I’m laying down in my bed and my fire alarms going off; but thank god I love the cold weather (Gainesville) because if my window wasn’t open, my neighbor couldn’t have climbed into my apartment and saved my life by calling 911. Cuz I guess by the time I got to the hospital, I had so much carbon monoxide poisoning and I suffered from a consequential stroke and I was seizing. When I got to the hospital they did a spinal tap and confirmed it was bacterial meningitis. My family was called and they rushed from west Palm Beach, and by the time they arrived, they had already removed my right side of my skull to relieve the pressure. Next they had to resect a lobe of my brain. Of course, I was medically induced in a coma for about 3-4 months where I had some of the most vivid dreams of my life (I see why Michael Jackson was addicted to propofol) when I finally woke up, I couldn’t talk yet which was probably the most frustrating thing, and I was freaked out when I learned what had happened and my whole left side was paralyzed. So what I’m wondering is, what besides quad extensions and leg press are really good for building your quads? I do everything that I’m able to one side at a time by the way, to avoid looking like an uneven retard. So my left side is much weaker from my stroke and less coordinated among other things.
