Anxiety or no??

Um, hi! I dont expect an answer on this, but I'm gonna say my problem anyway. Recently I went for my first job interview and of course I feel extremely nervous to the point where I can't really breathe right and feel like I'm gonna throw up. Then went back a couple days later to finalize some papers and the same feeling came back but a little stronger than before. And now when I think back to the interview and a couple days ago I get this intense icy-hot feeling in my face.

I just really need advice. Please help.🙏
