It seems that you have problem with stamina and reflect.
To get your stamina better, you have to do jogging or running oftenly. Do these exercises everyday or if you can't do it at least twice a week. It is better to keep doing it occasionally in all month than once but intensive.
To improve your reflect, you need a partner to help you. Find him and ask him to throw a shuttlecock to a corner of the court. after you can beat it, throw another shuttlecock to another corner. This make you run to every corner and it will help you much in the real match.
But if you can't find a partner for doing it, you can train by yourself. You can run between two box and move from one box to another. Keep the box beside you.
