How can i get rid of my coughing ?! please help me i've been coughing since july 2012 and i went to diff doctors but still i'm having this dry cough

Could be many things: Most common causes of cough: 1) post nasal drip 2) asthma 3) gerd (or a combination of the above). See a pulmonologist if you haven't already, as they should be able to rule these items out and look for less common causes as well.

Cough: Numerous causes. Often multifactorial. Have you seen a pulmonologist?

Lung doctor?: Have you seen a pulmonologist? Two possible targets. First, you can take medications that suppress cough regardless of cause. Second, you can run tests to find out the cause.
