Hi Angel, first of all - a big congratulations for already making it to week 4 of the program!! I truly believe CBT (really dedicating yourself to it and investing yourself in it) is the ONLY way to regain control of this disorder.
About your goals, I think the main question is - are you feeling more in control and more confident when you master the goals you have set? If yes, then your goals are working (like how you said you drive daily with your sister or to school etc); if not, then your goals may not be challenging enough. For example, if you have set a goal of driving a fair distance, is that because you are affraid to do that, and that fear is helping to fuel your anxiety? If so, then is it driving alone or driving with someone that causes the fear? Decide what is causing the fear, and then make that your goal - as long as it is challenging enough to make you feel more in control when you accomplish it - but not so challenging that you are not ready to tackle it quite yet and doing so too quickly will just set you back.
Basically, you just need to plan goals that, once accomplished, make you feel like you are making real headway against this disorder. If they don't do that - if they just feel like your usual every-day stuff, then they are not really goals and you should re-assess them and beef them up. But do take the program at your own pace, make sure you have enough goals accomplished and under your belt to make you feel confident enough to move on in the program.
That's my advice anyways. The two most important parts of CBT for me have been learning the techniques to control and challenge your thoughts, and the focus on goal setting as a tool to master the anxiety and lay it to rest.
