What should i do about the oral english?

I am so exciting to find this forum. My oral english is not good so I always lack of confidence when I have chance to talk with others. I have tried to watch BBC but it seems doesn't work too much to me. What should I do ?
Would somebody like to help me speaking it? By the way, I would be glad to help someone who need to practice Chinese.
Thank you guys in advance. I think my first step is to speak out my thoughts in this forum with you. Good luck to everyone!!
