Scabies 😖

I've been having some intense itchy and rashing for 3 weeks now. Finally went to the dr and she told it was scabies (although she said it might not be but where the rashes were located it was more likely scabies and to treat it that way just in case). I'm disgusted, annoyed and so depressed about this. I just don't understand where I could have possibly gotten scabies!! I now have to use some cream and disinfect the whole house throughly.. I really hope I can get rid of this damn infestation fast! Anybody have suggestions or happy endings regarding scabies? 😔
