Blood donation-revice

Failing to donate my blood frustrated me. I’m always happy to give my blood to people who need it. I thought it’s a good way to help people. I couldn’t donate my blood successfully this time because the nurse told me that maybe I was too tired to have a donation. I remembered that I had a basketball competition before the day I donated my blood. I was on the diet because I have to weigh my weight. I had stayed up late for several days. She also said that my hemoglobin is too low to donate. She had stabbed into my finger and inhaled three blobs of my valuable blood! I just couldn’t believe it and made my acceptation. Although I failed this time, I think I would donate my blood continually.
