Hi mate, ive just done an assignment on this exact topic and hope that I can help you, here goes:
I think that you are overly anxious, which leads to low or high arousal levels, meaning that you cannot perform at you're peak.
The reason you are getting anxious is because you dont have very much experience batting.
There are ways that you can improve on this though. Firstly, Positive self talk is probably the most useful, always staying in a positive mindset and saying positive things to yourself helps to clear the head after a poor shot. Secondly, Imagery is useful. there are two forms of imagery, one is personal, this is where you imagine the bowler through you're eyes, secondly, what I call public imagery is more like someone is videoing you. Personally, I always imagine Ian Bell playing the shot that I want to play, and think about how I can play that.
Just think, at the end of the day, cricket is a game and everyone fails at points. But the game is 90% mental and 10% skill, so if you are in the wrong mindset you will never succeed.
"I've missed more than 9000 shots in my career. I've lost almost 300 games. 26 times, I've been trusted to take the game winning shot and missed. I've failed over and over and over again in my life. And that is why I succeed." Michael Jordan
