I started a novel as lit fic but am thinking of going young adult because of the robustness of that subgenre. I've eliminated the profanities and some crudities but am concerned that that's not enough.

My protag was born in 1962 with Mullerian agenesis, which was diagnosed in infancy. By 16 she is obviously a virgin but sexually sophisticated in a clinical way. Her short life has included attempts at plagiarism, cold manipulation of her mother, a reputation among younger kids as someone to turn to with personal issues without getting adults involved, confinement in a mental hospital, a later suicide attempt, and a vivid dream about a man attempting to rape her. She got a part-time job at 14 and later used the money to buy a junker car. She is a pioneer of extreme running. But she is extremely secretive about herself and lives under a constant feeling that she is in danger. The book effectively ends when she is 17, but the second-last chapter fast-forwards to her 40s, and the last to her 70s or 80s.

Does this sound too heavy for young adults? If not, what age group might it be suitable for? All comments welcome.
