My dad is out of work for some time, my family is trying to be more frugal! How to cope!?

But, I am having trouble adapting. Call me spoiled or whatever, but I am just used to going shopping for clothes more than once a year. Even today I couldn't buy some eyeshadow with my mom because she didn't want to spend the money on it. I can't tell my mom how I feel because she doesn't really understand. I even didn't buy a dress for graduation this year and I feel so sad about it. The thing is i am very into fashion and beauty but it seems hard to be frugal when I am surrounded by things. HOw can I cope with this?
