You should apply for a normal Yeman passport that is factually correct in every way
... I applied to obtain American citizenship and then left everything and went back to my country
Did you 'apply' for or did you 'claim' US citizenship based on on your birth certificate?
More importantly, did you inform them that your parents, at the time of your birth, had a diplomatic status (i.e. were not 'subject to the jurisdiction of the United States')?
I traveled as a tourist to America in 2006 with a foreign diplomatic passport (noting that the date and place of my birth in the passport is completely different from my American birth certificate)
Were you a minor at the time when the passport was issued and traveled?
Collect proof that your father (I assume) was actually officialy appointed as a diplomat to the United States and accepted as such by the United States (the US State Department should have records of this, since they must accept such appointments).
If you have the passports they used at the time of your birth (showing under what conditions they were admitted to the United States), that will be very helpfull.
If your father was only visiting the United States, possibly without a diplomatic visa in his diplomatic passport, then it may very well be that they were 'subject to the jurisdiction of the United States' during that visit.
This must be properly documented.
With this information (where required with translations), have a qualified1) lawyer compile a letter that would accompany a visa application.
Goal of this letter would be to clarify the situation in a manor that all of the more complicated aspects are clear2).
Due to the present situation in Yemen, US documents should preferably be used2) where practical.
1): who understands exactly when a person is 'subject to the jurisdiction of the United States' or not
2): if your qualified lawyer doesn't understand the reason why, get another lawyer!
