STRESSED!!

Has any one ever gotten to the "I don't know" stage? Have you questioned your major? Because thats what I am going through right now. I don't know what the hell I want to do. College is a damn headache!! I don't know if I need to audit this class or just stick it out and see if I can pass it. Lord, help me!! On top of that I cause an arguement between my boyfirned and I last night. I didn't mean too, I'm just so stressed and he was there so I took it out on him. HELP!!!
