oh my! I'm terribly sorry you've been going through this. The ramifications of this horrific disease on self and family are truly heartbreakingly sad. I'm glad your hubby dragged you to the ER.
It's hard not to beat yourself up. You didn't cause this, your son still loves his momma and you will get stronger!! Can you take more time off work? It doesn't sound like you're fully ready to return.
Sending healing thoughts....lots of them
