1) I felt anxious at sentences 1-3 because I was waiting to see what you were writing about specifically, and these sentences seemed to drag out a bit.
2) I felt annoyed at sentence 2, because it seemed a little redundant, or it seemed like it could have been merged with sentence 1.
3) I was confused at sentence 12, because this appeared to be your thesis and I was expecting it to have been presented a bit earlier in the introduction so your reader would have a clearer idea of what you are writing about.
