Will I recover??????????

I have mild brain injury from being poisoned with cyanide and was wondering if Jesus cures people who are suffering from this, if they are suffering, it has been 3 years and still no recovery. Can Jesus heal me, a long time ago I was severely stressed out and I said "Jesus heal me." and I recovered but I dunno if I will recover from brain damage, right now I am crying in my room and don't know what to do, it isn't fair.
