All things are possible my friend. If you feel like donating blood to yourself, just believe, then you will achieve. Never ever ever ever ever ever ever let anyone tell you otherwise. I've heard of way too many instances where individuals allow others to tell them they can't do something, such as rob a bank... steal a car... go to war... or even become president. And I'll tell you this much, all of those things are possible. So go on and believe in yourself, because when you believe in yourself, incredible things will take place, such as making the impossible very possible. I'm just looking out for you. So there you have it.
Of course you can... you just have to buy some needles... withdraw the blood yourself... and put the blood in a freezer... store it until you need it. Then you'll just need to drink it, when you're in need.
You can only donate blood to yourself if you have your own blood type. For example, if you have blood type O then you can donate to anyone, including yourself. However, if you have blood type AB then you can't donate to anyone except for other people with blood type AB. So again, in that case you could also donate blood to yourself.
I've also asked myself on several occasions, "Can I donate blood to myself?" and I always end up thinking about how it wouldn't really do any good. Because if you think about it, the blood would be going into one arm, but coming out of the other. So even though you would be receiving a blood transfusion, you would also be donating blood at the same time, so it would kind of be like drinking your own pee.
I think the best way to find out whether you can really donate blood to yourself is to go ahead and give it try. You should be able to accomplish this with a couple of coffee straws and a bicycle inner-tube. I hope that you'll reply to this answer and let us know how it went!
