You injuryed your foot 6weeks had 3 xray and all doctor said you damage tissues in your foot 5weeks went back to the hospital and a doctor said you got a fracture why did there not told you first time?

Because in some smaller bones in the body e.g. the foot, the bone is so well supported by surrounding soft tissue a fracture is not visible on X-Ray. It is only weeks later when the fracture has calcified and begun to repair does the extra bone that is produced in healing become visible and hence it can be diagnosed. Another example bone in the hand is the scaphoid bone.

Don't blame your doctor for everything!
