Jameis Winston -- Thank God It's Over ... Let's Get Back to Football

Jameis Winston has finally broken his silence ... saying he's relieved that the rape saga is finally over -- and is turning his focus back to winning a national championship.

The Florida State QB just issued a statement, which he hand signed, saying, "It's been difficult to stay silent through this process, but I never lost faith in the truth and in who I am."

He added, "I'm very relieved I'll be able to continue my education at Florida State and I'm excited I can get back to helping our team achieve its goals."

There's more ... Jameis' lawyer, Tim Jansen, says the football star is considering taking legal action against the accuser for making the allegation in the first place.

Jansen says Winston values his reputation ... and feels it has taken a hit because of the situation.
