This seems like clear PTSD symptoms from his sexual abuse. He has re -entered that same situation he was in during that vulnerable time. I'm sure all the touring is bringing back unwelcome memories and since he and the others were never properly counseled or received any justice, or have never learned to accept and come to terms with what happened to them, he is somewhat spiraling. He needs the support of the people around him, instead of them pushing all their shared problems under the rug. I hope they all find peace.
