Feeling really guilty about my new phone

Now that I am (somewhat) less stressed, I am feeling really guilty about purchasing the iphone 6 plus. I'm going to rationalize by saying that I am no longer lusting after a tablet since the screen is so big, but I fear I may lust for a tablet at some point again. And one of the unanticipated problems is that accessories must be bought new. I'm not finding used or deeply discounted super-protective covers, etc. I'm used to picking up those kind of things on the way-cheap. And I missed one of the important hospital calls anyway because my family member knew my phone had been stolen so didn't try calling my cell. It seems I can't win.
