Should I drop a class? In need of serious advice!

Hey guys, I am in need of some serious advice. I have been teetering back and fourth and I am so stressed I don't know what to do. Here's what's going on...

I am a full time college student currently taking 4 classes (13 units) I am in math, English, psychology and theatre. When I spoke with a counselor one of the classes I needed for my major (psychology) was an arts class and she recommended theatre because it is an easy class with little homework that would be easy to balance with my other classes. So I took the class (fundamentals of acting) it's a beginner class. I thought there would be no acting, just learning about everything. I was wrong. The first day he told us what we would be doing and I got insane anxiety. I hateeee being in front of a group of people, let alone acting! I thought of dropping the class because I knew it would kill me with my anxiety. After speaking with my boyfriend and mom i decided to stick it through and just do it hoping that i would be okay and believing in myself and that I would benefit from going out of my comfort zone. Recently I have been thinking of dropping the class again because 1. My anxiety. I am nervous, and thinking about what I have to do days before I even have class just so stressed out about it. And then the day of class I have awful anxiety again. 2. I am having surgery next week and will be missing a week of school and feel like it will be very hard and overwhelming to catch up in 4 classes. 3. My other classes are kicking my butt and I feel like I should drop theatre to devote more time to my other classes that are difficult so make sure I pass. 4. This would be my first "W" on my transcript since I am dropping it halfway through the semester. Class started in august and ends in December) Since in halfway done should I just power through the last little bit of it? 5. A huge part of this is money. Since I am a full time student for my financial aid I get money for being a full time student. If I keep the class I will be getting $1400, if I drop the class I will get only $700. With a car breaking, and credit cards debt to pay, on top of plans I have for my 21st birthday I do not know what to do. I know my birthday isn't that important and I am fine with dropping my plans. I also have money saved up for a new car, this would only be adding to it. I am so indecisive about what to do and I need to figure my shit out asap. If you read all of this, thank you for taking the time to do so. What would you do if you were in my position? Any advice?
