It may have won the battle, but not the war. You retreated, you didn't give in. I know you have the strength to pull back, gather yourself again and go forward. Have you taken the medication yet? Try taking some benedryl--it's not prescription--before bed to help you get some sleep. That's what I had to do when I didn't sleep for three days straight because I was scared of the nightmares. It worked.

Look at all the positives that have happened for you recently. Even the horrible experience of making your way home to find you didn't have a key had many, many positives in it. The 'dolphins', the staff there, your new class, talking to people there. You've come to far to give in. You're simply resting from fighting and that's ok, as long as you know that you will get back in there!
