Heartbroken 💔

So my heart is broken... I had been dating a 26 year old and im only 17. I know that's bad. But I fell in love with him unexpectedly. Well my dad found out. He was mad but more disappointed in me than anything. He said that we can only be friends. At least until after I'm 19 and finish college. I don't know what to do. I feel like just dying... I know that sounds crazy to say over some guy. But he is so amazing and it kills me that we can only be friends. But I'm glad to have him in my life as a friend than not at all....
