I'm not sure if this will help, but you are not alone - I feel all of these things too. I jump from feeling confident in my app to feeling hopeless about it, and I certainly have good experience but many less hours than a lot of what has been posted here. And I, too, have to make decisions (financial, where to live, where to work, if I need to work, etc.), but cannot make them without knowing if I am going to school next year. It is emotionally exhausting!
At the end of the day, we are all strong applicants and we are standing together. I know it helped me to read that other people feel anxious and frustrated with being unable to plan, so hopefully it will help others to have one more voice in the choir.
