All the fears and ponderings that really choked me up (I believe mine were exactly along the lines of yours), I kept in a box deep inside. Then I would think about it only a bit at a time and when it started to pull me down I'd lock it back in the box. These are fears of things not within my control, so they don't get free reign. I can't control other people, only myself. This is part of the process of division - going from one unit into two separate parts again. Just allow a little bit of exposure each time, feeling my way around each step I knew would come. I would also push through the pain, imagining each scenario and how I would feel so it wouldn't be so raw when it really happened. After you lock it down, don't let it wiggle out again - switch activities or give yourself small assignments to do in order to keep you from dwelling and pulling yourself in further.
