Forehead/Skull reduction

Is it possible to reduce the size of my forehead? I do not mean lowering the hairline, because my hairline is already low. My forehead is vertical and almost seems as if I do not even have a forehead to begin with. The shape of my head is very strange. As most people's head is round or square. My head is like the roof of a house, being pointed at the top making a sort of 60 degree angle. I can feel and hear my head always cracking as if its not stable or solid. I am also not sure it bone can be molded or change shape but I have been able to compress my head through pressure. Very very painful but I was desperate. With a 30 minute span however, it would return back to its original shape. I most know if there is some way to mold my cranium to a rounded shape?
