<p>I agree, it is important to believe that you did all that you could do and that the rest is out of your control. That will make sleep a lot, lot easier. You need to also be content with the option of not being at Yale. When I went through my bouts as well, one of them being the option that I was definitely not getting in to Yale and that I will be fine. This way, I will have gotten through all the difficult parts of each option. See if that works :)</p>
