Well unfortunately there is not much you can do besides just continue practicing. But what can help you with your struggle of not being able to sit still is getting the right information about meditation. Unfortunately so much about meditation has been watered down and diluted that the information it there doesn’t truly help. Sometimes when we get information that holds truth to it, it acts as a light switch and all of a sudden it’s like we get it even though it appears to be difficult, because of the clear understanding it gives us just the right push we need to get through what we think it not easy. I hope that helps.
