Sounds just like me when I was learning. It took a couple of months before I started hitting the center of the runway. I wasn't afraid of hitting myself with the plane but I was afraid of hitting someone else. It was all mental for me and I got lucky one day and was at the field with only my flying buddy and we just took off and landed all day. Eventually I got off the grass and onto the runway. What a great feeling. Shortly after that I did my first loop and was actually laughing and giggling out loud. it's great when you progress and each step you make increases the level of fun. Oh yeah and don't feel bad if you hit the grass every so often everybody has interesting landings.
