Idk what to do.

I never buy myself anything. I want to buy a custom shampoo & conditioner made just for me but I feel bad about it, it'll help my dandruff plus it'll keep my hair hydrated and healthy during these winter months but i still feel horrible about wanting to actually purchase it!! Ive paid rent and my phone bill but i know for a fact someone will complain about it. 😫😫 I save most of my paycheck so thats not the issue, its just whenever anyone buys themselves something in my household my aunt thinks its stupid and makes a huge deal out of it and it stresses me out so i don't like to spend money on myself.
