Sounds like you are being smart about your spending and like Dakoda said "I look at it as money spent for medical purposes...my mental health! LOL!~" If it is helping you (withour ruining you) then I say no worries.
I look at it this way..........sometimes when times are tough, we talk about our "comfort food"........well you are getting comfy things for your home so THAT is your comfort food. It's just knowing not to let it get out of hand.
Enjoy your new "comforts".......
