Tired of my family

I pay bills while my OLDER sister gets to lay around and be a lazy ass bitch. I even took over her designated bill when she lost her job to help my parents. I can't even spoil myself or save money due to helping with bills and groceries and basic necessities. If I even ask my parents if I can not pay one bill just one time they fkn guilt trip me. Like are you for real?! You want me to be better in life yet I'm suffering because you spoil the little princess 😒 I'm so close to just stopping my designated bill payments so they can pay it themselves they always shopping anyway and wasting money on shit that they don't even NEED. While I am running out of soap and need new shoes or clothes yet don't because I don't want to spend money so I can have a bit saved. Just so frustrated. Yet they don't understand. Sure I live here but I pay for all my own things. I drive myself places myself. I feed myself. While she rejects job offers or doesn't apply because she doesn't like the damn job place. 😠😠😠😠 just need somewhere to vent because I can't trust NOBODY to vent to without it getting back to my family.
