How do you tell your grandmother???

I’m turning 20 tommorow… I graduated in May… My grandmother has been so kind as to have taken me in 10 months ago… When it came time for me to go to the art school I dreamed of my whole high school career… she told me that I was stupid, I was cutting off my nose dispite my face, because I would be paying back student loans for the rest of my life and living on the streets because art makes no money… So I signed up for community college, hoping to find a carrer that would intrest me… but the fact of the matter is I am misrable… I know she loves me but I don’t paint anymore, I don’t sew anymore, charcole sits in the bottom of drawers waiting to turn to dust… my paintstaint ecentric wardrable has been replaced by what she calls “sutable for a functioning young adult.” She knows every intamacy of my life… I know she dose it out of love… but I want my long hair back… I want black hands and a paint stained face, I want to be surounded by the smell of terpinoid and liquin again… It is quite literally like stabbing a knife into my heart and wresteling out my sole… the fact of the matter is I have made alterintave plans… I have signed up for a school on the other side of the country… I have gotten together my arrangement including a plane ticket… I know that I can chicken out and pretend nothing ever happened with no ones knowledge, but, that would be an incredible waist of time and money… and I have decided no matter what happens I will go even if she follows me to the airport throwing a fit… but she has a bad habit of starving her self and getting sick when she gets upset… so how do I tell her… I know she will most likely be upset but I just don’t want to cause her to compramise her health.
