I share your frustration! I have two hatchlings. One I got about 8 months ago and one about 3. My advice is one of two things
1) be patient
2) be prepared to deal with a less friendly turtle.
It look my turtle almost 6 months of good care for it to become "friendly". Although to be honest, I am not sure if he is friendly or simply realizes that I am going to feed him, not eat him. We can't expect turtles to be as friendly as dogs and they definitely do have their own personalities. Now Slider (the friendly one), swims towards me and follows my finger around. He also will calmly sit there basking when I walk by. The other(Junior) is still a big chicken and will bolt everytime anything moves near him. Junior may get better with time or maybe he is just less friendly.
People may get mad at my analogy but I think of them as more interesting fish (i.e. living in their quasi-natural habitat and me watching them do their own thing). As opposed to a dog whether you expect bonding and playing around.
if the turt starts acting "friendly", its great fun and so cute. However, you can still have a good time raising your turts even though they don't turn out to be the "eats from my hand and plays with me" type. But give it a bit more time.
