Gee Silver_queen, I'm real sorry your dad isn't being supportive to you.
When I was way young, about 14, my mom saw how I had self-injured my arm and leg and she said nearly the same thing as your dad has said to you. Please know-- that was not a good thing for him to say to you-- he doesn't understand.
Seeking support from others that understand is best ... like posting here.
Not sure if this is possible for you... but, I moved out when I was 19. I ate noodles and toast for months, bought my clothes at a used clothing store--didn't have a phone for 4 months as it took me that long to save up the money for the connection fees. But you know--- I LOVED my independence!!!! No one to judge me or cause me to feel worse about myself. Perhaps... an inexpensive place is out there for you??
You are a wonderful woman..... I hope you know that.
PM me if I can ever be of any support.
