[رجلُ من سفَر]

Well, as I said, the first sentence is absolutely correct

I dare say you mean that it should be an adj ...nervous

but this is not true, If you use the word (nervous) your sentence will be

wrong in this case

but the second one has a little mistake ,where you use (nerves) the

wrong way, so like I mentioned, the correct word for this sentence is

nervous

Any way, set your mind at ease and use these common formulas

get me upset ....

get me nervous

.......daze me

.......confuse me

Have a good night, and ease my mind about your marks "scores"...for

this day
