Cleverley concedes the hate mail tha was coming his way was difficult to take.
He told manutd.com: "I'm not going to lie and say that I was enjoying my life at that time. Football was my life.
"I was playing for a club that I loved, I'd worked so hard to get there and I could see it falling apart. It was devastating.
"You get letters at the training ground. You try to respond to fan mail, but in the end it gets to a point where you're better off not reading it.
"Social media was just a hindrance, so I closed my accounts. Having a lot of followers on Twitter meant a lot less to me than my mental health and my football career.
"I just got rid of it all and I've never gone back on since. I think that's been good for me."
