Donation Blood but Now I'm sad!

I'm very interested in blood donation and I make this donation a time in every four month. Last July 7, I met a very sorrowful condition because doctors at Yangon Blood Donation Bank didn't accept me to donate blood as 27th time. My haemoglobin state is very poor and , if I donate my blood again, it's very dangerous to my age.I proposed the official doctor to test my CPA , they tried for me but the result was definitely poor. I try to donate again but in vain. I really feel sorry for not donating blood and can't have a chance to donate blood within two months.
My friends and students, all together 40 people had this chance at that day.
They comfort me that I can provide them to get that chance and so I should be pleased at that point. Although they give me encouragement, I can't help thinking about that case again. Now I take medicine to refill my haemoglobin regularly and I also hope to donate blood within two months.
Please my beloved mother, brother, sister, teachers, friends and students, pray for me that I will get that chance in very soon.
I also wish you that all of you can get that chance instead of me now.
Please comfort me by doing this donation. OK?????

I do hope I can really donate my blood again and again to the end of my life.

Whenever I donate blood, I always pray for a gift to get again the chance of healthy blood donation in every four month. This is my only and one wish for donation blood. I feel sorry whenever I see patients who really need new blood to regain their age. Do you know how they need your blood donation?
Please trust me they need your help...
Let's make a hand for our society.
OK...?

Now I feel sad.
