My colleague said, “if I were you, I couldn’t tolerate, I will quit.” I said, “if not because of my knee pain, I would definitely look for a new job.” She said, “Even though you find a new job, the employer doesn’t know you have a knee pain.” I said, “but they will find out sooner or later. If it would effect my work, it still will be failed.” I went to attend a volunteer activity and I saw children who have leukemia. I realized that everything — such as health, happiness — is not we should have. They are blessed. My physical therapist refused to treat me anymore. Actually he wants to treat me, because he can get money, but the insurance doesn’t cover it anymore. I can’t pay, he can’t continue. I went to see a new doctor, he found the problem, but he can’t solve the problem.
