Johnny Manziel isn't done.

That was the message he parlayed in a post on Instagram Monday, saying "I'll be back... In time. It can't end like this...it won't."

"jmanziel2 You all write about a day in my life and what goes on...here it is. No secrets, no hiding, I''m not what you read about. I'll be back... In time. It can't end like this...it won't. I love you all even though your comments suck."

Manziel also tweeted at Texas A&M fans Monday, apologizing and vowing to make things right.

Manziel was replying to a tweet of his highlights from Texas A&M from an Aggies fan blog.

Manziel was released by the Cleveland Browns earlier this off-season after two years of ineffective play and too much partying, and hasn't received any attention on the free agent market from other teams.
