I'm so sorry to hear that the "bug" is still reeking havoc on you and your family and I pray (something I'm usually not prone to do) that you won't have to endure the misery for much longer and all will end up well for the holidays!
I'm afraid at this time I'm just repeating what all the others before me had already said, in that by sharing your darkest thoughts won't make any of us think any less of you, but even more. Kitti, you're a very wonderful and special lady for whom I now I have a greater respect for.
Yea this is scary stuff you are facing, but ironically, by finding it within you to share it with us tell me you will also find it within you to work it out so it will no longer have any hold on you.
