Argh, I'm so pissed off and it's all 90% because of this fracking FR!

For this FR, I'm assigned to do the data and results portion. Frankly, I don't like this portion. I even prefer the answers to questions part than this. But that's not why I'm so effing frustrated and annoyed. You see, to calculate for the reduced viscosity, I need to know the concentration of the albumin solution. If I follow the volumes listed in the lab manual, then I'd know the concentration. But my professor asked us to change the amount to be prepared. I forgot the freaking amount he said, and now, I can't freaking compute for the freaking concentration, which means I can't freaking compute for the reduced viscosity, which means I can't freaking move on with this freaking FR! And I am freaking pissed off!

I don't even know if I should be pissed off at my prof (why does he always have to change the increments anyway?!) or at myself (why did I forget the volume?! Why didn't I write it down?!). I'm sooooo freaking pissed off. ARGH.

This is so frustrating! I can't believe that one. effing. number. is what's keeping me from getting this FR over with! I'm not even sure if finding out the volume would help me move on with this FR.

HELP ME.
