Suggest Treatment For Obsessive-compulsive And Attention Deficit Disorder

My family and I believe that I suffer from obsessive compulsive disorder, possibly schizophrenia and attention deficit disorder, I have been diagnosed with the latter and I do have obsessive routines, counting things, fidgeting, opening and closing lighters, things like that. I hear things pretty often, nothing threatening just voices, quotes and such, and I always see things moving in the corner of my vision. Shadows, sometimes faces, people. Animals on a few occasions. All this really interferes with my ability to concentrate on pretty much anything, academic or otherwise. Please let me know what you think. Trevor Driscoll 19 years old
