I was going to go ahead and try to donate plasma but the problem is I'm worried about the pain. How painful will this needle be? If doesn't even bother me that it's a big one, I'm just so worried about the pain.... The first time I got a needle In me I honestly felt like it was stabbing me but it only lasted for a few seconds, the worst part was the anxiety, and the fear. The stabbed feeling only lasted for two seconds, probably less. In fact it didn't feel like stabbing, just a deep, painful weird feeling. Sometimes when I get too freaked out I feel like I'm fainting, or about to faint.
