I saw it in highschoool and it had a strong impact on me at the time because i was troubled somehow but not for the same reasons like the main character. I used to go to a psychiatrist as well and i loved the interaction between the two and the final cathartic scene. I thought it was a very good, realistic and inspiring movie at the time and i still believe that though at times , watching  again when i was older i still think it's a bit slow.
Raging bull is another kind of movie, though...really loved de Niro in it but i'm not sad the movie didn't get an Oscar.
