Matt is going to WWE-sponsored rehab.
From PWInsider:
Matt Hardy posted a video this evening announcing that he is going to enter a three month rehab program to get himself well. Hardy specifically thanked several WWE personalities, including Vince McMahon and Ann Russo, noting that they were going to help him.
Hardy, who became emotional towards the end of the announcement, noted that he had been self-medicating himself due to a number of injuries and over the last year, it had gotten the better of him. Hardy said that over the last month, he was trying to get himself clean and used "something else to balance" himself out, which is what led to his problems in recent weeks.
Hardy stated that his plan was to complete the rehab program, open a wrestling school and get back to being the "old Matt Hardy."
On behalf of everyone associated with the site, I sincerely wish Hardy the best of luck in getting himself and his health back together. I truly, truly hope he can do everything he needs to do for himself and his family so he can enjoy the quality of life he and they deserve.
