sweet Deli,

living in the dark is not an option!!! would it be possible for you to go to (or at least call) Austin T (who is your T after all) and say, I am having a very hard time with feelings of rejection thse days, ... for example what do you think of this... and just lay it all out.
Since you know that they both know each other, you might get some useful news, or you might get a volunteer of help in contacting him, or you might get help with feelings of rejection....
sorry if this is not helpful, i am wanting to be helpful. Your university paperwork is VERY important, is now not one but three documents needing to be done - good grief if not by him then by SOMEONE, and besides you have questions of your own that need to be answered.
