Violagirl, I'm going to be brutally honest with you, as someone who's been on both sides of the fence.
The bottom line: both of you are probably right and both of you are probably wrong.
I've TA'ed lots of labs and they can be very frustrating. Understand that you're one of probably 30 or so students that TA has to teach and patrolling the lab making sure you don't kill yourselves is an exercise in patience in itself. I can agree that some TAs have terrible attitudes about teaching, but their responsibility is to make sure you learn the material and don't hurt yourself. Being your friend or making you comfortable in lab is completely optional. Your professor may empathize with you, but are you prepared to deal with it if she doesn't? I can say she will almost certainly not take any action unless your TA is doing something inappropriate like sexually harassing you.
I've noticed that you've posted a lot in the Organic forum lately, basically asking people how to answer the questions for your lab reports. It doesn't show good initiative on your part, and I bet that comes through in lab. I ALWAYS knew which students hated lab and were only there because it was a prereq for their biology degree. They may as well have stamped it on the front of their shirts. Basically, instead of logging in face time with your TA or your professor, you've resorted to an internet forum full of strangers. And now you're proposing to go complain to the professor that your TA is mean, but you don't go to office hours and you appear to be struggling with class. Try to understand how that looks. I believe that your TA is a jerk. I also believe that you aren't trying your best. The important thing is to figure out a way to bridge that gap.
My suggestion to you is to start going to office hours for either your TA or your professor. You might be surprised how positive that ends up for you. I can tell you that as a TA, when you're grading lab reports or exams and you're not sure whether you should give a point to someone, you will almost always give it to a student who comes to office hours a lot because you recognize their effort to improve.
