What is the best way to balance the stresses of senior year?

Kamryn, it's good that you're recognizing the signs of stress building. There are the obvious and tried and true principles to reducing stress - exercise, eating well and getting enough sleep. You should work on those but additionally I would recommend a self-reflection exercise that goes like this: What are my primary goals at this point in my life? What is the underlying fear that's creating the anxiety around those? For example, is it fear that I won't be successful, fear that I won't be self-sufficient? fear that I won't accomplish my goals, fear of what people will say or think? Once you have identified the true fear and (you may have to go down a few levels to actually uncover the true fear), you can begin to take action steps to address that fear. You should also identify what will happen if you don't meet your goal (it really won't be the end of the line), you will always have a plan B. So, identify what that is and write it down as well. Breathe deeply and keep moving.
