Plasma and Emotions: Please read on?!

Plasma and Emotions: Please read on?

I donated plasma for the first time yesterday. Afterwards I sat there for 15 minutes and felt fine. I even stopped at a gas station before I got home to get a gatorade. I live on the 3rd floor of my apartments, and as soon as I started up the stairs I almost blacked out. I finally made it to my apartment, but I felt sick the rest of the night even though I drank a ton more of water and juice and had healthy meals.

Now today I woke up and I feel like a total basket-case.
I have been crying for no reason, and things that usually don't bug me are making me so crazy and upset that I cry more.
If I get up quick from sitting or laying down I still get a little dizzy, but I'm not to worried about that. I just have never felt so sad/upset about stupid stuff this badly before in my life!!!

Does the way I'm feeling today have anything to do with donating plasma yesterday, or am I just having a really bad day?

Just as a side note: the reason I'm not too worried about the almost fainting and feeling dizzy afterwards is because it says in the hand-out that is a possible side effect. And I am a pretty light-weight.

Some of both. Keep getting good meals and plenty of liquid. You should be fine by tomorrow.
