My own instinct, if I in your position, would be to seek short-term agency work (in any relevant field) and then see if it was possible to move into a full-time position from there.
While I wouldn't rule out a possible switch to IT, there's nothing in your c.v. to date that leaps out at me as saying that it would be the ideal field for you. (I've got a maths degree, and I've taught the subject at A-level, but I'm not confident that I could handle complex coding and I'm almost certain that I wouldn't enjoy it. So IT might not be the best path for you, I feel).
You might get some possible pointers for your future by using the skills assessment tool here or by using the other links (or even, possibly, by calling an adult careers adviser):
