The only thing that could kill your flying permanently would be some kind of permanent, neurological vertigo.
Getting out of the hospital you're probably hopped up on a number of medicines. Seems like most of them have vertigo or dizziness as a side effect. So talk to the doc and see when you can get off them, the sooner the better.
A few years ago I was prescribed propanolol(beta blocker) for a problem. It fixed the problem, when I remembered to take it. I didn't take it everyday, but after crashing two planes on bottom outside corners I finally figured it out and stopped taking the medicine when I didn't really need it.
Later on I was prescribed a couple other medicines. They turned out to cause some real dizziness, and upset the coordination between my eyeballs. It was extremely difficult to fly on a bright, partly cloudy day. My eyes wouldn't focus and twisting around going up and down made flying difficult.
Now that's over and I've taken the advice of Igor Trifinov, three time world combat champ. Train your inner ear(or vestibular training). Just learning, again, to stand on one foot and gradually work at moving your arms and legs out and about while standing straight, or even bending over etc. you can relearn a lot of stability, and strengthen the muscles that do it. Another excercise directly for the inner ear(start slow on this one and do it somewhere safe if you start to fall). Stand up straight, raise your arms directly overhead with your fingers pointed straight up. Slowly turn around. If you don't get dizzy, great start. Then try turning a little faster two or three times. When you are starting to get dizzy you'll likely find your feet hitting the ground at odd angle and in odd positions. So stop and try again a bit slower. The trick is to learn to use the info from your feet and your peripheral vision when looking straight up to keep yourself upright and ignore the inner ear problems. With some practice you can learn to fly without being bothered by any dizziness. Many fighter pilots have to learn this. Something like 50% often get vertigo is air combat maneuvering.
Don't give up. Doing some strength and weight training, and various excercises also helps. The body takes more maintainence as it gets older. Eventually it looks like I'll be training, eating, sleeping, and nothing else. Hopefully at 100.
