Frustration is not the operative principle.  I am calling your attention to
salient points in response to your request for help.  I have not expressed
frustration.  I have repeated points that needed to be highlighted because
they answered your question, before you repeated it.  This is to help you, and
has nothing to do with my feelings.

My style is to state information, baldly and bluntly.  It is the points that
matter.  You may assume that I have no feelings whatsoever for purposes of
discussion.

If I were to express feelings (were I to have any), I'd say something like, "I
feel ...", or I'd make a blatantly /ad hominem/ remark.  There will be no
doubt as to whether any feelings are expressed, nor inferences required.

Moreover, do not feel that you have to justify your actions or your questions
in any way, other than the technical basis thereof, at least not for my sake.
 State your actions and your questions; that'll suffice.

When I pointed out that "you apparently ignored" an alternative, that was a
statement of a conclusion based on objective evidence.  Had you responded to
that advice, for example asked for clarification on parts you did not
understand, that would have provided counter-evidence.  The evidence for my
assertion was that you made no modifications whatsoever to the code that was
giving you trouble, despite several answers to your specific question, nor
asked any questions about that advice, then repeated the same question about
the same part of the code.

If you have trouble with specific terms, it's always useful to go back to the
basics.
