Ashley, I too used to feed Purina without any problem. I'm thinking that maybe some of the newer Purina variations may even be better. What I am concerned about is that you will be taking on so many adult responsibilities while still in high school. I don't know anything about your situation, but would hope that you are not making these decisions without giving it a lot of thought. You are a very sweet girl and deserve to have some help in the areas of which you spoke. You might want to see if you could discuss your situation with a high school counselor or some other responsible person who could help you assess your options.
