Hi Khaleed,
This is one of the commonest problems of learners of English throughout the world. Relax, you are not alone. One of my teachers told me that 'One must be exposed to the target language in order to speak in it.' You should bare in mind that you must try to speak wherever or whenever you are. When you are alone, you can translate your ideas or whatever you see into English...
Don't ever give up!
Good luck
