Take a break and then try again. I am left-handed and dyslexic so patterns give me fits. I tend to go with simpler patterns, but even then I have trouble sometimes. I know which patterns I cannot do, so I don't even attempt them. Finally, sometimes a light bulb will go on in my head and I know what I am doing wrong. It helps to have someone to share your thoughts/frustrations with. Hope you have such a person in your life.
