Not happy with my life

Hello everyone, I am a Volleyball player and I use to play for my nation. Currently, my age is 22 years old and I have played 3 national for my state. It was a good time but once upon my right leg started not to work properly. I realized that there is no strength in my right leg and because of this problem I was unable to play volleyball properly. Then after when I told this problem to the doctor he clearly said that this is a major problem because your leg started to get paralyzed. Guys this statement was worst for me. I know how I handled this situation. And now my condition is like that I am unable to play volleyball even I cannot run for 200 meters. My leg does not work in a sufficient manner. Guys please help me and tell what can I do seriously I want to play volleyball in my life.
