as someone who was raised to be frugal a lot of this stuff feels kinda shameful almost but when i stop and think about it i stand by my assessment that its actually cheaper this way  if you think of it in terms of per use cost instead total cost it will ease your guilt  if you use it more or use it up cost per use will be pennies  if you use it once or twice or never then the cost per use is greater  this will either prompt you to use the thing you bought or think twice before you buy it  another way to not feel guilty about being wasteful is to sell it or give it way unless its spoiled food of course   i grew up frugal too and the adhd tax for me is having too much crap  i either forgot never got got to it or thought i would uselike more than i really do and cant seem to part with it of the guilt  when i realized that i cant clean and organize more than 5mins at a time i started not buying something that i dont think i will use  sometimes window shopping or putting stuff in the virtual shopping cart and not checking out is just enough to satiate the consumer beast
