I'm so sorry he's hurting you. I have no advice only to say that it's pretty soon. He's still a baby and probably still a bit traumatized by his life so far. I think time may heal a few of those issues. He may never be a cuddler but then again maybe when he's more sure that you are his furrever mom and will always have food he'll settle down. Chalk some of it up to kittencraze! Good luck!
