Hi momcj, little to add to the previous sound advice.
It's perfectly understandable that you are worried, and indeed a little frightened to take the 'dating' step again.
One thing to bear in mind - all experience, even bad experience, helps make us who we are.
This time your eyes are open, and you have no expectations, so at this stage, you have nothing to lose.
it would be a shame if a past experience ruined a future one - so although it feels a little scary, allow yourslf to feel a little thrilled at the same time.
Best of luck - let us know how you get on.
