What a rough week.
Sometimes, you can only do what you can do. Every now and then, life takes a very real, terrible turn and it can take all we have just to hang on, much less work on ourselves. I think you deserve a lot of credit for not running to food to deal with your emotions - after having only two weeks under your belt, that's very well done indeed.
I'm so sorry for your friend's loss - I can't even imagine.
