Chicken or Egg?

As you know if you read my last post, my son has a contagious rash that is really geeking me out.  In addition to making me a nervous wreck, it is also so time consuming to deal with.  The cherry on top is that this virus is like a modern day leprosy and we've had to put all social gatherings (besides the birthday party we'll be attending for a max. of 45 min. today wearing a long sleeved shirt and pants to make sure we don't spread this crap- keep in mind the heat index in Atlanta is about 110 degrees this week) on hold until we've got it under control.  Have I mentioned that my son and I are both super social beings who go stir crazy at home by 10AM???

Addendum:
(Just to be clear, the CDC states,

"Molluscum contagiosum is not harmful and should not prevent a child from attending day care or school."  

We are being overly cautious in an effort to prevent the spread and thus bandage L and wear clothing that covers him thoroughly.)

Below is a photo of some of the products I am using to try to combat this thing:

The routine takes place at least three times a day and includes no less than 7 or 8 products at a time.  Since molluscum is also typically prevalent only in immuno-suppressed persons, I have the added concern that something besides being covered in wart-like growths is wrong with L.  My logical side tells me that he is fine and healthy, has only been sick once since he was one year old, and that it is probably just introducing him to more cow's milk products in an effort to overcome his allergy/sensitivity that caused his immune system to take a brief dip.  My anxious, guilt of a PPD mama side is beating myself up for not breastfeeding him for longer and not being able to control the spread of the rash better once he did contract it.

So, my question is, is it being a PPD/PPA Survivor that predisposes me to worrying above and beyond what I assume the average mother does...OR, was it my pre-existing anxiety and controlling tendencies that spawned the PPD in the first place?  I've been pondering this all week.  I mean, since I am well and all, and have been for a couple of years, am I now a worrier of the same proportions I would have been had I not had Postpartum Depression?  Or, would I be less of a worrier if I hadn't lost it postpartum, making my brain more susceptible to worry and anxiety?  I don't know that there is a universal answer to this question.  In fact, I am not sure that any amount of research could possibly tease out a definite conclusion for this "chicken vs. egg" dilemma.  But I am interested in hearing what your experience has been and what you think.  Which came first???  Let me know!
