Too Much WTF

Deep breath....because....because I am going to cry. No, not cry...wail. I keep holding back the tears and keeping the stiff upper lip but all I can do at this moment is weep. I am weary, friends. Weary of so much shit hitting me day after day after day. The latest and greatest just within a 24 hour span;
-scheduled 4 interviews with potential nannies to take over for Aero's current caregiver who leaves on May 11. All four were no show without even a phone call or email.
-Single dad, who owns the house, going through a divorce, sits me down to let me know this shared living situation is not working out for him and I need to find a place to live. Great. I just got rid of all my furniture to live here.
-Caregiver informs me last night that he feels obligated to a friend who is going through hard times to drive her home to Utah. That means his last day is not on May 11, but TWO days from now.
-Aero has been battling a cold for almost 3 weeks. No appetite, losing weight and he is already to small.  Lost all ground on oral feeding and back to strictly g-tube. Started antibiotics for possible sinus/ear infection 3 days ago and not seeming to make a difference. What is wrong? Is his immune system all out whack and why? If you know the genetics of a child with Down syndrome, you understand they have a very compromised immune system. So, please no platitudes about how he will bounce back. I am really worried.
I don't know what to do anymore. I scared, I am confused as to the next step. I can't continue with all this WTF stuff.
Universe, why?
