The vast majority of people find their jobs boring and awful. That is reality. I have asked before but don't recall the question ever being answered. What is your age? The reason I ask is because you write about things that are adult-oriented but you are very dependent upon others (for example you write in your post about learning cooking skills) so I think "well maybe I am wrong and she's a teenager.

If you are an adult, I think you will have the most success in learning skills that will create a more independent life for yourself. Cooking, paying bills, coping skills for life's problems, will all be things that will give you a sense of accomplishment and assist in helping you create a life that is separate from your mother and sister.
