"feel difficult"

[Lim Choon Yen]

Hi all, can anyone tell me if my sentences are correct?

A.) "I feel difficult doing the assignment."
B.) "I find it difficult doing the assignment."

I think both of my sentences are correct but someone says that it are wrong and it shall be "I have difficulty doing the assignment." and " I find it difficult to do the assignment."

A is incorrect; B is marginal.

Both of the suggested alternatives are better.
