Welcome to the board Jabberwalkie!
I'm so sorry to hear that this has happened to you. ::BIG HUGS::
I think you need to ask yourself, what do I have to repent for? You did not thing wrong other than get sick! If you repent for something you didn't do, you will be excusing those liars...that's simply unacceptable.
My mother, once a pioneer as well (now disassociated after they disfellowshipped my father for a nonreason - he was a Ministerial Servant) would say "Everything happens for a reason." I know it's cliche, but more often than not it's the truth.
I know you're asking why me? We've all been there...heck I still ask that...but that will reveal itself in time. Right now you focus on you...get the rest you need, get the mental rest you need! Take some time to download...maybe even take a vacation...go watch the air go by.
Again, welcome. You'll find a lot of cyber support here. You're not alone in this anymore. Remember...all of this has happened for a reason.
