I ted a guy. And now I feel terrible. Help?

Okay. So ive only been talking to this guy for about 5 weeks. And he asked me for nude pictures before a few times before, but I didnt. And he asked me again last night, and was being really cute so I did. But they werent nude. I was just in my bra though. And I think hes 17 and im only 14. He also asked me to talk dirty to him multiple times. And I didnt reply. And he hasnt texted me all day. So im scared that he showed the picture to other people, because he may be mad that I didnt talk dirty to him. And I really feel like im going to throw up. Ive felt like it all day. And next year im going to the highschool and its going to be so weird seeing him around. Cause im not really the type of person that does things like that. Its not me. What can I do about this? If anything :/ thanks.
